Lighting Building Exteriors

Lighting Design 1You have pulled out numerous stops–just to make that house, building, backyard and its surrounding of yours look superb. So, why let all your labored work go in vain when, with a glide of a switch plus some strategically positioned landscape exterior lights, you can confidently roll back the dimness and let the display do the talking?

When done right, exterior lightings can turn your environment into a bliss. They help highlight any home’s architectural features—something which will obviously draw attention to the backyard.

Whether you are looking for architectural or even security outdoor lighting, the right systems will definitely provide that visual oomph in addition to a safety boost to your home or business building.

Security Is a Key Factor

There are so many reasons that can prompt you to light your outdoor area. The most obvious one being safety and security. The lighting requirements for a parking lot is dependent on traffic. However, this shouldn’t worry you because recommended illumination levels can be obtained from the Illuminating Engineering Society (IES). Carefully observe its suggestions to avoid possible insecurity issues.

Safety: Safety means staying safe from tripping over an obstacle or walking into a tree and the required light levels for this are actually very low. One can see quite well in the moonlight and that’s just about 0.02 foot-candles.

Security: On the other hand, security refers to protection from people and threats. To achieve a considerable sense of security for your property, you’ll need to boost outdoor artificial lighting. If you are in the garage or parking area, you need to know if someone is plotting to mug you. You also need facial recognition to choose between fight and flight. And picking such visual cues requires an illumination level of 3 foot-candles. A safe outdoor is very important to any home, building or organization, so be keen to provide sufficient lighting in the exteriors.

 The Power of Aesthetics

Lighting Design 2The other reason for enhancing your outdoor lighting is aesthetics. Remember, lighting is an important feature of attracting renters to your property. So, it should be taken seriously. You want to ensure that your building looks open and inviting, just like a community beacon.

Exterior Spaces Require Attention

Illuminating outdoor spaces entails paying special attention to light fixture position, intensity, and color in addition to duration. When properly combined, these factors will surely realize the right lighting design that is capable of achieving safety, efficiency in terms of energy consumption, and cost reduction.

Exterior Lighting: The Golden Advice

Exterior lighting is effective at giving dimension to any building plus the surrounding landscape. However, they are not all about flooding your surfaces with light. You should highlight small. This means highlighting a few structural parts with a vivid spotlight. Showering the walls with twinkles of light can create a dramatic effect, giving the exterior a different appearance at dusk. However, when designing your exterior lighting fixtures, consider the texture, brick & stone color and steelwork.

Exterior Lighting – The Power of Going Architectural

Rather than simply lighting your exterior space with ordinary bulbs, use architectural lighting to brighten it up and add some elegance. But, take caution not to create glare or light pollution. Also, consider other users (for instance those inside) since badly placed lighting can cause glare-related problems to other building users.

Façade lighting: Making Non-engineering Decisions

Façade lighting Façade lighting 3Façade lighting is not about numbers. Of course, engineers will compute the vertical luminance, luminance plus uniformity values for your building—however, that isn’t the prime goal.

You need to make numerous non-engineering decisions. For instance, determine if you are intending to let the building blend in /stand out. Are you after a subtle or “in the face” effect? Which colors do you want?

Making your building look “wow” is down to your aesthetic judgment. In case you are unsure about your decisions, consult an exterior lighting designer, an architect, or planner about your target effect. Remember, it’s always better to highlight certain parts of the building as opposed to flooding the entire façade with uniformed light.


Color Characteristics of LEDs

LED color 4There’s an array of different LEDs that are available in the lighting market today. The diverse LED characteristics comprise of light color or radiation wavelength and light intensity among other features.

These color characteristics are as a result of an assortment of factors during the manufacturing process. Factors such as semiconductor make-up, fabrication technology used, and encapsulation are also important in determining the LED color appearances.

Understanding LED colors

Color is a fundamental feature of light emitting diodes (LEDs). Initially, there were a limited number of colors available for these fixtures. You could only find red LEDs.

However, as technology advanced, there have been significant improvements in LED materials and colors.

Color Characteristics of LEDs: Color Temperature

One important aspect of color appearance is color temperature, which exemplifies how cool/bluish or how warm/yellowish technically white light appears. CCT Correlated Color Temperature (abbreviated as CCT), is actually a metric correlating the source of light appearance to a pre-heated theoretic dark/black body appearance. As a black-hued body gets hotter, it becomes red, orange, white, and ultimately blue. The CCT value of a light source, provided in Kelvin (K), represents the temperature at which a hot black body closely matches the light source color under investigation. It symbolizes the color of emitted light and not that of illuminated objects.

What is Color Rendering Index (CRI)?

Metrics Color representation has numerous distinct forms, including reference based systems, gamut based systems, and systems which are built upon sophisticated color appearance models.

CRI refers to a measure of fidelity (that’s how ‘true’ a certain light source is when related to a reference source), but it doesn’t address the issue of color appeal and discrimination.

Chromaticity and LED Colors

LED colors1Chromaticity refers to an objective interpretation of the quality of color irrespective of its luminance. It consists of two distinct parameters, often described as colorfulness (s) and hue (h). For a specified CCT, a light source with a positive Duv value has a chromaticity which falls above the locus of the blackbody (appearing slightly greenish), while a source featuring a negative Duv value has a chromaticity which falls below the locus the blackbody (appearing slightly pinkish).

The Influence of LED voltage drops

The LED voltage drop often lies between 2 and 4 volts. The actual voltage that occurs across the two terminals is highly dependent on the type of LED/materials used and influences the color of LED in question.

As expected, the voltage curve of an LED broadly resembles that of a forward diode characteristic. But once the diode is switched on, the voltage becomes relatively flat for various forward current levels.

LED Characteristics: The Summary

The following table gives a summarized insight concerning LED color characteristics.

Wavelength Range In NM Color Of the LED Voltage(V) at 20MA The Type of Material
Blow 400 UV(Ultraviolent) 3.1 to 4.4 AIN, AlGaN, AlGalnP
400 to 450 Violet 2.8 to 4.0 GaP,AlGalnP
450 to 500 Blue 2.5 to 3.7 lnGaN
500 to 570 Green 1.9 to 4.0 GaP, AlGalnP
570 to 590 Yellow 2.1 to 2.2 GaAsP, AlGalnP
590 to 610 Orange or Amber 2.0 to 2.1 GaAsP, AlGalnP
610 to 760 Red 1.6 to 2.0 AlGaAs, GaAsP, AlGalnP


Below 760 Infrared Below 1.9 GaAs, AlGaAs


Besides LED color, the following are other major LED specifications:

  • Light intensity value( denoted as Iv)
  • Current vs. voltage specification
  • Reverse voltage
  • Angle of view

LED Specifications for Operational Life

LED colors2LED’s light intensity doesn’t diminish with time. What this implies is that LEDs have a specific operational life. This specification helps determine the application of different kinds of LEDs. LED specifications are determined by the following formulas.

L70% = The time taken for a 70 percent illumination (this is also known as lumen maintenance)

L50% = The time taken for a 50 percent illumination (also known as lumen maintenance)

Note: According to LED standards, your LEDs shouldn’t exhibit any major shift in chromaticity.

These figures’ rationale is that 70 percent lumen maintenance is equated to a 30 percent light output reduction. This’s an approximate threshold figure required to detect to gradual light output reductions.

A Guide to LUX Levels

LUX 1Light Level, also referred to as Illuminance, represents the amount of light that is measured on a surface (which is plane). Or, it can be described as the total luminous flux incident that strikes on a plane surface. It is measured per unit area and is commonly known as LUX.

Understanding LUX

LUX, also called DIALux is increasingly becoming popular in the modern world. You can now plan in DIALux with great luminaires from the world’s most renowned manufacturers and enjoy ultimate freedom in the lighting design process.

Benefits of LUX

Featuring professional light planning, LUX is extremely simple and effective. It utilizes the latest luminaire data and state-of-the-art software that’s always available for free. The colored light scenes with light emitting diodes (LED) are energy efficient and guarantee excellent illumination for all your buildings including outdoor spaces.

Recommended LUX Levels

The level of lighting in the outdoor is approximated to be 10,000 lux, albeit on a normal, clear day. However, for a building, especially in the areas that are closer to windows, the LUX levels may possibly be reduced to 1,000 lux. On the other hand, the middle area may register a 25 – 50 lux. Consequently, you may need additional lighting equipment to compensate for these low levels. For precision & detailed works, the level of light may range between 1500 to 2000 lux.

LUX 2In homes- The recommended illumination levels for homes is often 150 lux. The living and dining rooms may work pretty well with about 25 to 50 lux.

Supermarkets- Working spaces like supermarkets and mechanical rooms require light levels of about 750 lux.

In offices- The normal workstation requires 500 LUX while the ADP area and conference rooms require 500 LUX and 300LUX respectively. The auditorium requires 150-200 LUX while the training room and internal corridors should be supplied with 500 LUX and 200 LUX respectively.

The table below represents the light levels for different workspaces.




(Lux, lumen/m2)

Public areas featuring dark surroundings



Warehouses, theaters, homes, archives


Simple orientation meant for short visits


Working areas involving occasional visual tasks


Easy classes


Showrooms, normal office work, a study library, PC works


Detailed drawing and mechanical work, operation theaters


Supermarkets, office landscapes


Performance of prolonged & exacting visual tasks


Performance of extremely special visual activities of very low contrast & small size



Factors Affecting the Effectiveness of Illumination

The effectiveness of illumination is usually affected by several factors, including light quantity & quality, contrast, amount of flicker, shadows, and intensity of glare. To optimize illumination in security, emergency, and safety situations, consider adjusting each factor differently. Lighting standards also play an important role in the design, installation, durability, and efficient distribution of illumination.

Measuring and stimulating Light Level – Illuminance

Illuminance is measured in foot candles (ftcd, fc, fcd) or lux (in the metric SI system). A foot candle is actually one lumen of light density per square foot; one lux is one lumen per square meter.

•        1 lux = 1 lumen / sq. meter = 0.0001 phot = 0.0929 foot candle (ftcd, fcd)

•        1 phot = 1 lumen / sq. centimeter = 10000 lumens / sq. meter = 10000 lux

•        1 foot candle (ftcd, fcd) = 1 lumen / sq. ft. = 10.752 lux

Calculating Illumination

Illumination is calculated using the formula = Ll Cu LLF / Al (1). In this formula, I denotes illumination (measured in lux, i.e. lumen per m2), Ll represents lumens/ lamp (i.e. lumen), Cu is the coefficient of utilization, while LLF is light loss factor and Al is the area/ lamp (measured in m2).

Light Planning: The Steps

Light planning is a five-step process. The actual process involves:

  • Planning objective analysis
  • Planning conditions analyses
  • Overall planning
  • Detailed planning
  • Documentation

Understanding Glare

Glare can be categorized into two groups: discomfort and disability glare. The level of discomfort glare can be measured by determining the glare index in accordance to the UGR method. This is often graded on a scale, which ranges between 13 and 28 where the greater the glare index the greater the degree of glare. The smallest variation in the glare index designating a significant difference is three.

Reflections from reflective glare or materials can usually be avoided by adopting the following strategies:

·         Choosing convenient luminaire positioning

·         Using materials for all reflective surfaces

·         Selecting fixture with effective screening and low luminous intensity

·         Picking out luminaires with a bigger surface area

·         Choosing light colors for your ceilings and walls

Balance is key

LUX3A well-balanced luminance is essential to boost visual clarity, effectiveness of the ocular functions of the eye, and contrast sensitivity. You should always avoid high luminance which can cause glare, intense luminance contrasts that may cause visual tiredness, and low luminance contrasts, which trigger a staid atmosphere that doesn’t stimulate.

New Ideas on Lighting Design

Lighting Design 1Modern lighting design is all about incorporating ambiance, task as well as accent lighting. Ambient will provide your home with overall illumination while the task lighting will be responsible for directing light to specific work zones. On the other hand, accent lighting will help highlight explicit objects.

However, within these basic requirements exists tons of new lighting ideas. So, whether you are looking for something fun, or want something a little bit subdued, there’re virtually endless new lighting ideas for each and every home/room.

Go for A Robust Assortment

Do a clever mix of different lighting types and strategically place them at different locations in your room if you want to create a proper, layered, and robust lighting scheme.

What About Two-in-One

Use two dissimilar types of overhead (also called ambient) lighting. This adds elegance to your living room. For instance, include pot lights (which help provide the bulk of light and spread it across the entire ceiling) and a suspended transitional fixture to emphasize your living room’s seating area.

Multiple Fixtures Can Be Incredible

When it comes to a large living room, it’s always better to go for pot lights– a single overhead fixture might be insufficient. However, if you aren’t into recessed lighting, you can hang multiple fixtures all through the room. But keep it simple and go for fixtures featuring clean silhouettes. Suspend them on a grid, and not to any random spot.

Ceiling Accent Brings Class

Lighting Design 3Think outside of the box and light around the edge of your ceiling to achieve your dream accent light plus create a unique detail. This will accentuate the unique architectural niceties of your ceiling and breathe some aura of elegance to your living room.

Consider an Nice Arc

Don’t have ceiling lights? Well, don’t worry! There is a solution. Just design a central source of light featuring an arc-like floor lamp

Sculptural Sconces

Make a statement by embracing exceptional sconces. But ensure your up-to-date sconces are adjustable, permitting you to adjust the size, and the direction of the light. They provide an exclusive and sculptural element that is capable of setting a contemporary tone for your living space.

Built-In Accent Will Just Kill It

Include an accent lighting fixture into your built-in shelving to highlight special objects as well as accessories. This will immediately draw eyes to your lit-up shelves, creating a bright and exquisite focal wall.

Visual Balance

Visual balance can be tricky. However, it’s very simple. Get a table and floor lamps. Then place them on either side. This will help your guests (who are sited at either side) to receive light equally.

Consider Mix & Match

Lighting Design 4Who said that you must match your lighting sources? Make a bold statement by going the mix and match way. For instance, you can add chandeliers and sconces (which are very classy) to table lamps (which are considered modern). Moreover, you can mix old and new ones to give your living room a sense of character plus personality.

Other ideas

Consider hanging a statement fixture, highlighting the architectural details, think beyond your living room, and trust your instincts.


LED Drivers : All You Need To Know

An LED driver refers to an electrical device that regulates the power supply to a string or LED. It responds to the changing needs of the LED device by providing a consistent amount of power as its electrical properties vary with temperature.
IP67 driver
With outputs that are compatible with the electrical features of the LED, a LED driver may offer dimming through pulse width modulation circuits and may include several channels for separate control of various LEDs/LED arrays. Without the right drivers, LED fixtures may become extremely hot and unstable, thus causing poor performance or even permanent failure.

LED Drivers: The Different Types

There are many different types of LED drivers categorized by the output voltage, output current, maximum switching frequency, form of packaging, and supply voltage.

Each channel’s output can range between 250 µA and 50 A, with common chips carrying an output current of 20, 25, and 100 mA per channel. The commonly available voltage sizes are 2.3 to 5.5 V and 3 to 5.5 V. However, you can readily find LED drivers bearing a supply voltage of up to 630 V.

  1. Constant Voltage

Constant voltage LED drivers can be obtained in numerous manufacturing standards and are designed to meet high specifications for quality and efficiency.

  1. Dimmable LED Drivers

By dimming your LED lights, you get the freedom to enjoy different scenes. You can create a romantic atmosphere in the dining room, or establish a spectacular viewing experience for your guests during office presentations. You need a dependable LED driver that meets all electrical requirements if you want to dim your LED lighting system.

Dimmable LED Drivers: Understanding LED Driver Dimmer Controls

LED drivers with dimming capability offer the flexibility of dimming the lights from 0-100% while maintaining color and temperature. Remember, dimming an LED light can also reduce the operating temperature of your fixture, ultimately boosting LED efficacy as well as lamp life.

In the olden days, LEDs and dimmers weren’t always so expedient. But as technology advanced, powerful dimming controls entered the market to add more definition to their performance. To effectively control your LED light intensities, you’ll need to fix a dimmer that’s compatible with the LED driver you intend to use.

3.0-10V Dimming Drivers

LED technology is virtually taking the market by storm. Complimenting a 0-10V dimmer with an already power-efficient LED lighting is not only efficient but also effective. A LED lighting high-quality dimmer (powered by ERP LED driver) can help users save big on costs associated with energy consumption. Moreover, they assume a superior control capability when compared to other lighting applications.

LED Drivers: Their Applications

LED drivers can be used as:

  • Industrial, outdoor, residential, and commercial lighting
  • Automotive interior, tail lights, and portable flashlight
  • Signage and LED backlighting
  • Garden and elevator lighting

LED drivers: How to Select the Right LED Driver

When you’re searching for reliable LED drivers, you should take into consideration several attributes, including Output Voltage, Supply Voltage (-0.3 to 20 V, 2.7 to 5.5 V, and 3 to 5.5), as well as Maximum Switching Frequency ( between 200 Hz and 200GHz). You’ll be able to get the right chip that’s suitable for use as a high-power LED driver, dimmable LED driver, constant current LED driver, RGB driver or 24v LED driver on an integrated circuit or any other circuits that might require such driver chips.

The benefits of LED tubes over fluorescent tubes

Incandescent Vs. LEDFor years, lighting up commercial spaces and residential homes was a no-brainer. It involved a lot of planning. Most folks simply stuck with linear fluorescent lights (abbreviated as LFLs) — and for some good reasons. First, they offer quality light output; they are efficient and have a fantastic lifespan. In fact, the T8 lamps used about 40 percent less energy as compared to their older counterparts T12 lamps, which are now phased-out. Now, comes a new player in the commercial lighting area, which has great promises of offering better efficiency: the linearT8 LED tube.

The big question

 So the question is; does the T8 LED tubes have what it takes to swap out your tried-and-true linear fluorescent lights (LFLs)? To help you make an informed decision, this article is going to walk you through the benefits of T8 LEDs:

 Mercury Free – The absence of mercury-free is a big plus. Unlike fluorescents, light-emitting diodes contain no mercury, making them some of the safest lighting systems for the environment in the market today.

 Dimmable – Most LED lighting systems possess full dimming capabilities, while fluorescents are very expensive when it comes to dimming them and perform so poorly.

 Directional Lighting – With LEDs, you can achieve directional light (i.e. they can illuminate exactly where you need them to). But fluorescents are characterized by multi-directional lighting. This means that some light is likely to get lost in the fixture as well as other unnecessary places.

Works fine with controls – Most fluorescent lighting systems tend to burn out quicker even when integrated with common occupancy sensors as well as other controls. On the contrary, LED lighting systems work perfectly with all control systems, thanks to the fact that their life is not dependent on turning them on or off.

 Superior efficiency – The newest LED Tubes are about 30 percent more efficient their LFLs counterparts.

 Quality light ­- Today’s LED lighting systems can output light in an assortment of color temperatures that are similar to fluorescent but do not experience any flickering issue that is common with most fluorescents.

Lifespan – On average, the life of a LED lighting system is 50,000 hours, while that of LFL is about 30,000 hours.

I Vs. LED Shatterproof (potentially) – Most LED tubes have been designed with a shatterproof coating. However, with linear fluorescent, one had to either order a specific shatterproof fluorescent lamp or utilize a tube guard which can be very costly.

The only issue with LEDs is the initial upfront cost. However, with rebates, several tax incentives, as well as huge energy saving capabilities, you are likely to see a high ROI faster than you would expect.

The golden advice

It is vital that you first crunch the numbers (that applies to your particular situation) to determine whether that initial expense really makes sense as far as your business is concerned. You should conduct a thorough cost/benefit analysis and consider all factors when choosing between LFL and LED. Also, do your research.  Ask the experts. But, one thing for sure is that LEDs are better than LFLs.

A Guide to LED Emergency Lighting

E1LED Emergency lighting is usually meant for emergency situations where the primary power supply gets disconnected and every normal illumination fails. This could result from a power cut or a fire outbreak. It’s essential that LED emergency lighting automatically operates fully and provides sufficient illumination to enable all occupants to leave the premises safely.

So, if you are considering LED emergency lighting system, here is all you should know:

LED Emergency Lighting: The basics

Most buildings nowadays incorporate sophisticated LED emergency lighting fixtures installed during construction; the design of equipment being chosen by the architect as per the current local authority requirements as well as Building Regulations. Emergency LED lighting is often sub-divided into standby lighting and emergency escape lighting.

Cost matters

Generally, the decision to utilize a self-contained LED Emergency Lighting system or a central battery will probably be determined by cost. If an installation is durable and has low maintenance requirements, then central batteries, though quite expensive, might be ideal for larger projects. Typically, costs and luminaries are major issues of concern, especially on smaller jobs, and it’s this criterion that makes the self-contained systems more popular.

LED emergency lighting driver temperature

Ensure that your LED emergency lighting has been subjected to aging plus electronic load tests. This helps to ascertain whether the LED emergency lighting panels can withstand excessive temperatures. This guarantees performance, safety, and stability.

Emergency escape lighting

Emergency escape lighting refers to that part of the emergency lighting system, which supplies illumination for the safety of persons vacating a location or attempting to end a potentially hazardous process beforehand.

Standby lighting

Standby lighting is often provided to allow normal activities to continue substantially without being changed.

Consultation and design

The first thing to do when installing LED Emergency Lighting escape illumination is consultation and design. Both the fire risk assessor and the designer should meet and make comprehensive decisions on where the system is required and chalk up a plan illustrating the type of power supply, the locations to be covered, facilities, duration, and mode of operation.

The next step…..

Having decided on the type of LED emergency lighting system you’d like to install, then go ahead and choose specific positions for the lighting signs and units within specific premises. This will then help you choose the right equipment. Remember, emergency LED lighting signs should be carefully sited in order to create clear exit routes that lead to the ultimate exits from the building. Where the exit isn’t identifiable, a visible sign should be utilized instead of a lighting unit. Special concern should be paid to directional changes, individual stairways, floor level changes, corridor intersections, plant rooms, and toilet areas. Access to firefighting equipment as well as fire alarm call stations should be properly illuminated.

Mode of operation

Mode of operation is a vital factor to consider when choosing LED Emergency lighting systems. Thus, you should take into considerations principle factors like maintained or non-maintained. The use of the premises in question determines whether to go for a maintained or non- maintained LED Emergency Lighting system.

LED Emergency Lighting Advantages

• Installation is extremely fast and affordable
• Low hardware material costs
• Standard wiring material might be used
• Reduced maintenance costs
• Burn-through will automatically fulfill the need for luminaries to be lit
• No unique sub-circuit monitoring requirements
• Increased integrity and efficiency

LED Emergency Lighting: Disadvantages

• Testing requires isolation
• With varying environmental conditions throughout the system, the batteries might be severely affected by high or low ambient temperatures
• Battery life is often limited to four years, depending on the application

Bottom line

E2LED Emergency Lighting systems have become very popular these days- thanks to their low energy consumption, efficiency, and flexibility. However, before you rush into getting your LED Emergency Lighting system, it is vital to understand the basics (what they are and how to choose the best). The above guide will help you in getting the best.

The advances in G9 LED capsules

CAPSULE 1With the escalating need for new lighting systems, it seems you are living in the world of new trends, where the possibilities of emergent technologies are endless. New lighting systems like G9 capsules (popular lighting systems) have continued to rock the lighting industry. The G9 capsules are ideal in small spaced settings that require a higher amount of light. Since their discovery, these LED options have continued to be a whimsical alternative to ancient halogen capsules. The G9 LED capsules save energy, are cheaper to run, and do emit the same amount of light as ancient halogen capsules.

With that in mind, here is what you should know about the advances that have catapulted the LED revolution.

But, first get the basics right.

Why move from watts to lumens?
Watts is a measure of how much energy the light bulb uses, while lumens are used to measure the amount of light the lighting system gives out. Similar to watts, the higher the value of lumens, the brighter your light will be. For instance, a 1521 lumen bulb (which is a 100W equivalent) is brighter than an 800-lumen bulb (which is 60W equivalent).

G9 LED Capsules

G9 LED Lamps & Capsules can be direct replacements for G9 halogen capsules, however, they can be a lot larger than normal halogen capsules; so, it is important to check if they will fit into the fitting or not. It is also imperative to check that the LED G9’s have adequate ventilation because otherwise the LED’s or internal drivers can overheat resulting in failure.

G9 capsules are LED in nature. As such, they emit minimal heat, which makes G9 capsules efficient and energy-saving. In fact, they can save up to 88% amount of energy as compared to standard capsules.


The Omni-directional G9 LED capsule is  indisputably effective due to the fact that they emit light equally, effectually as well as multi-directionally. Moreover, they do not heat up –which allows the LED capsules to be surprisingly efficient and reliable. Most G9 LED capsules feature a warm white color which perfectly suits interior living areas.

G vs. ES

The most common type of light bulb is indisputably the Edison Screw (ES) light bulb. Actually, ES is the threaded connector which Thomas Edison had patented and utilized. These types of bulbs are available in sizes like E11, E14, as well as E17. The numbers denote the base size. On the other hand, the “G” in G-type LED bulbs represents “glass,” from which they were initially made.

The G-Type revolution

CAPSULE 2Invented towards the end of the 19th century, the G-type bulbs offer a fantastic alternative to conventional bulbs to circumvent Edison’s patent. That is why they have a unique base shape. Similar to the Edison Screw bulb, the G bulb is manufactured in different sizes, the G9 light bulb being one of them. The “9” is meant to denote the actual number of millimeters in between the 2 adjacent pins.

1. Wider beam angle

With a 360° beam angle, the G9 capsule bulbs offer the widest beams you can find on the market today. So you only need a fewer number bulbs to light up larger spaces.

2. Durability boosted

They last over a decade.

G9 technology takes care of how long your LED lighting system will last. The technology ensures that your lighting system lasts for at least 25,000 hours, which is about 15 years (on average use) of service.

The bottom line

LEDs are ruling the lighting sphere. They are efficient and consume low energy. That is why, if you haven’t embraced this new trend, you are missing a lot. Try G9 LED capsules today and redefine your living space!

Buyer Guide To LED Tubes

TUBE 1Purchasing lighting systems used to be a cinch. When your 80-watt incandescent burnt out, all you could do is simply buy more 60-watt bulbs. However, incandescent could waste lots of energy and created warm a glow. Consequently, they were phased out. As technology advanced, energy-saving CFLs were introduced to replace incandescent, temporarily, and as time went by, LED tubes arrived in major electrical stores.

Solicitous choice for your living room

Energy-efficient, long-life, as well as environmentally friendly, LED tubes are the solicitous choice for any modern living room. Contemporary LED lighting choices are becoming more and more diverse.

They can last 30,000+hours and feature relatively low mercury content, which ensures that they have negligible environmental impact.

T8 LED tubes

T8 tubes possess excellent color rendering capabilities, which vividly bring out the details of your clothes as well as furniture. Common settings where T8 LED tubes can be used include retail stores, auto garages, modern offices, schools plus conference rooms. These come in a variety of lengths 2 foot, 4 foot, 5 foot and 6 foot with the most popular being the 5ft led tube.

The diversity of LED tubes

LED lighting fixtures possess exceptional directionality features, which makes them a great option in lighting applications like task and reading lamps, pendants and overhead, accents and displays, cove lighting, outdoor and landscape accent lighting, linear strip lighting, ceiling cans, and stair as well as walkways. LEDs can also be used in art lighting since they do not produce Ultra-Violet (UV) radiation, which makes them safe for artwork.

Buying Exclusive LED Flat Panels: The Secrets

PANEL FLAT 1With tens of thousands of LED panels manufacturers as well as suppliers in today’s marketplace, it might prove hard to choose the best ones. As such, you must be careful, especially if it is your first time with the LED revolution. A quick glance should offer you the LED insights so as you can pick exclusive LED products capable of saving a substantial amount of power and even last longer. So, the following factors should be of help to you in deciding the best LED panels that can serve you for many years to come.

Light guide plate plus its driver

The LED panel’s quality is dependent on the light guide plate along with its driver. The light guide plate determines the light transmittance as well as power conversion efficiency. The power factor and the life span of the whole light system are determined by the driver. As such, it’s vital to ensure that you don’t compromise on the quality of these two important factors when purchasing panels. For instance, the 600×600 led ceiling panel has been manufactured with precision to serve you for years to come.

The right panel system

Flat LED PanelNow that you understand how crucial the two are, let’s deep dive into how you can select the right LED panel system:

Selecting LED light guide plate: Go for panels that feature light guide plates and those with PMMA light guide plates after only half year of usage, such as the 600×600 led panel. Well, PS materials are popular in most countries across the globe, thanks to their affordability. However, it can easily turn yellow and get dark spots –something that can decrease the panel’s power conversion efficiency. Moreover, PMMA material has an ant-aging and possesses superior light transmittance capacity as compared to PS materials.

• Selecting LED light panel driver – Large driver cripples are the major cause of LED light flickers. Typically, a superior PF value must come with a flicker, which cannot be detected by a naked human eye but. Since a low PF value driver utilizes lots of energy as well as power, a predetermined PF value is needed on LED drivers (typically 10+w panel lights). Due to the high cost, existing drivers with high PF value mostly have flicker.

Other performance factors

The following factors should also be considered before purchasing LED panels for your specific needed.

Aluminum Frame

Go for LED flat panel lights (like the 600×600 led panel) that utilize aluminum housing (environmentally friendly) featuring rapid heat dissipation, anodized, as well as anti-corrosion properties since they are long lasting and have superior performance. Some of the shortcomings of inferior aluminum panels are low heat dissipation capacity, general weakness, reduced chip life and rapid fading light.

LED light panel driver temperature

PANEL FLAT CEILING 4You should ensure that your manufacturer has conducted aging and electronic load tests on the LED panels. This is to ascertain whether the panels can bear extreme temperatures (101℃-138℃). Panels that pass this test tend to perform better, are safer, and stable, which makes them long-lasting. You can count on panels like 600×600 led ceiling panel when it comes to bearing extreme temperatures.

Insurance and warranty

Insurance is meant to protect LED panels against manufacturing defects and assure you of the product warranty. The manufacturer in question must offer you full support when it comes to warranty claims and subsequent repairs/ replacements.

LED light luminous efficiency

Ensure that the luminous efficiency of your LED flat panel light is 120l+m/w. Also, check that it has no flicker and has a top power efficiency of 0.9+. Also ensure that:
• It has high CRI (Ra>80)
• The THD is less than15%
• The DLC is under 4.0 standards.
