There are a spectrum of technologies used in energy saving light bulbs. This category looks at the technologies used today and for the future

Why Light Output Should Be Measured In Lumens & Not Watts

Lumens vs. Watts1As light emitting diodes become the standard lighting, it is important to understand the dissimilarities between watts and lumens, as well as how to establish the right amount of lumens for achieving optimum atmosphere in a space.

Lumens vs. Watts

Let’s get to understand what lumens are: The lumen is an international scientific measurement standard for the quantity of light generated by a specific light source or its measured brightness. On the other hand, Watts measure the required amount of energy necessary for operating a light source.

The only challenge here is that there isn’t a mathematical formula to convert watts to lumens, like in converting kilograms (Kgs) to miles.

Think Lumens, and Not Watts

Lumens vs. Watts2The advent of LED technology (which is more energy efficient) has changed the lighting landscape. It has rendered the use of conventional bulbs meaningless. Unfortunately, this rapid change in technology has made the old-fashioned “Watt” light measurement less able to accurately indicate the bulb brightness. This does not allow for the different efficiency in conventional types of lights (i.e. filament bulbs, halogen & fluorescent) and LEDs.  This is why light output should be measured in Lumens and not watts.

Thus, the energy industry is now opting to use a more stable as well as widely-accurate unit to measure light intensity commonly known as Lumens.

Understanding Lumens

Lumens (abbreviated as lm) is a measure of light emitted by a lamp/ bulb (but it must be visible with the naked eye). The greater the Lumens number, the brighter the light.

Understanding Watts

On the other hand, watts don’t measure the brightness, rather the amount of electricity used.

Bulb Luminous Efficacy

Lumens vs. Watts3The effectiveness of bulbs is expressed in terms of the lumen-to-watt ratio. This is the number of lumens produced for each and every watt consumed.

The rate of conversion of watts to lumens by bulbs varies and is dependent on the technology used. Lighting bulbs producing more L/P (i.e. lumens-per-watt) are cheaper to run since they generate more light and use less power.

LEDs possess the highest L/W ratio—what this means is that they are capable of generating a higher amount of light (from the bulb in question) for relatively little energy.

Longer-Lasting and Energy-Saving LEDs

The introduction of LEDs tremendously reduced power parameter requirement for buyers. This is because you’ll be getting a bulb fixture that’ll cost you 90% less as far as your electricity bills are concerned. What’s more, these bulbs are likely to last longer. Producing less heat as compared to incandescent bulbs helps LEDs to realize a 50,000 hr. lifespan.

So, when shopping around for a replacement lighting bulb, think of lighting fixture that’s brighter, longer-lasting, as well as more energy-efficient—the LEDs.

Lumens vs. Watts4

Lumens vs. Candelas

The two measurements can be confusing and are similar. However, they have subtle differences. Lumens are used to measure the amount of light emitted (i.e. the total visible amount of lights from a given source). This is also known as its luminous flux. On the other hand, candelas are used to measure the luminous intensity. It is also important to note that candelas are more predominant in America, while the EU prefer lumens.

IP Ratings Explained

IP Ratings Explained111The IP ratings (an abbreviation for International Protection ratings) is a two-numbered representation for protection against solids and water. The first digit represents the protection rating against certain solid foreign objects (such as dust) while the second digit is the actual protection against water.

Understanding IP rating for lights

The IP rating (Ingress Protection) is an internationally recognized method utilized to describe and measure the level of protection of electrical appliances against water and other technical components. It’s always advisable to choose the right IP rating for your exterior lights plus ceiling fans so as to prevent hazardous accidents.

For enclosures, the emblematic “waterproof” IP ratings include IP67, IP66 & IP65 enclosures.  The table below explains the meaning of each of these ratings and how they’re arrived at.

IP Ratings Explained1

IP Rating The actual Protection offered Description of the offered protection Test Method
IP65 Enclosures These ones can protect against any water jets Water entry is projected by a nozzle (which is 6.3 mm long) against enclosures from all directions and must not have any harmful effect. Test duration: The test takes about 15 minutesWater volume: It requires about 12.5 liters of water per minutePressure: The test requires a pressure of 30 kPa at a 3m-distance
IP66 Enclosures This one can offer protection against water jets Water is projected in dominant jets (i.e. a 12.5 mmNozzle) against enclosures from all directions and shouldn’t have any harmful effects. Test duration: It requires about 3 minutesWater volume: The test requires 100 liters of water per minutePressure: The test must be done at a pressure of 100 kPa and at a 3m
IP67 Enclosures These ratings can protect against an Immersion of up to 1 m It protects entrance of large volume water and when the enclosure in question is immersed in water(but under pre-defined under pre-defined pressure and time conditions) Test duration is 30 minutes The immersion should be at a depth of more than 1 m measured from the  bottom of the device and more than 15 cm measured from the top of the device

 

IK Rating: What is it?

IK ratings denote the European standard EN — the equivalent of IEC 62262 (2002) standards. This represents an international numeric classification concerning degrees of protection by enclosures for all electrical appliances against external mechanical forces/impacts.

IP rating in electrical appliances

The IP Code is an International Protection Marking that interprets the IP code as an Ingress Protection Marking. It also classifies & rates it as the level protection against intrusion, dust, unintentional contact, as well as water.

IP ratings brief history

IP Ratings Explained1111111IP ratings were first developed by the International Electro-technical Commission. They are mostly used in Europe & Asia, but find some adherents in parts of North America.  Since they’re international standards, testing and certification is done by the TUV and not UL.  Note: IP ratings were developed to address harsh environments and not ultraviolet rays (UV) protection. Thus, engineers should incorporate additional materials that offer UV protection.

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
Below 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.

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.

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.

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.

Omni-directional

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!

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 lifespan 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.
