LED, Halogen and Compact Fluorescent Lamp- CFL technology energy saving light bulbs from SLB will help sustain the environment for future generations but
additionally save a considerable amount in electricity when compared to traditional light bulbs. They can pay for themselves in a few months, making them a sound investment.
Saving light Bulbs-SLB provide high quality energy saving bulbs for a wide range of home and commercial lightings applications.
The technologies offered include, energy saving CFL which offers good savings at an economical price,
halogen bulbs which offer good aesthetics and the new LED technology which offers much higher savings but the LED bulbs are more expensive.
At SLB we work directly with selected quality manufacturers minimising overheads and consequently we can pass
outstanding value to our customers.
Energy Saving Light Bulbs- CFL
The Compact Fluorescent Lamp- CFL technology energy saving light bulb will save around 80% in electricity when compared to
the old fashioned light bulb. This means that is a good cost conscious choice for lighting homes and commercial properties. Our CFL's are high quality light bulbs
with a long life expectancy of around 10000 hours and the CFL's reach full brightness quickly making them the ideal choice for saving money and the environment.
The aesthetics of a halogen lamp is very good with an appearance similar to a conventional light bulb and the additionally they will save around 30% in electricity against the
incandescent filament light bulb. SLB halogens are dimmable which will reduce electricity consumption even further when the
illumination level is dropped to create the mood setting you need for the space.
LED Bulbs- 2 Year Manufacturers Guarantee
When looking at the different types of energy saving light bulbs, the LED bulb is the ultimate winner as it will delivery around
an 88% electricity saving when compared to standard lamps. Not only can you save a small fortune in electricity but the life expectancy is between 30
and 50 times longer. Our LED lamps are exceptionally high quality and accordingly the manufacturers offer a 2 year Guarantee

The light bulb was invented by Thomas Alva Edison in 1879 and since this date the electric light bulb has revolutionised the illumination of homes and commercial buildings. Edison produced an incandescent light bulb and acquired a patent but it took a further year to perfect the product as the filaments kept burning out. He tried 6000 different filament materials before finding a carbonized filament solution which produces a light bulb with a life of 1500 hours. In contrast the filaments of later incandescent light bulbs were made from tungsten. The electric light bulb was a most significant invention which superseded gas lighting and candle lighting which is demonstrated by the fact that the incandescent lamp has lasted until recent times. It is only now that due to technological advancement and the environmental focus that the incandescent light bulb is now being replaced by energy saving light bulbs.
Energy Saving Light Bulbs
The light bulb has lit homes and commercial buildings for over 100 years and it is only in recent times that technological advancement and environmental pressure has resulted in the creation of energy saving light bulbs. The first technology was fluorescent which first appeared in strip lights known as fluorescent tubes. The technology has always been appropriate for energy saving light bulbs but the dimensions needed scaling to allow this to be made into units small enough. This was achieved by using long thin tubes either in a linear loop design or more recently in a spiral shape to produce a long thin compact fluorescent tube which forms the basis for the energy saving light bulb. The other modification was to incorporate an integrated ballast to start illumination.
The compact fluorescent lamp ( CFL ) was the first energy saving bulb technology. Initial CFL bulbs saved a considerable amount of energy but suffered from rapid flickering and produced a dull light when first switched on. The CFL technology has now advanced and high quality CFL bulbs are now largely flicker free and reach a good level of brightness almost immediately. The other advancement in CFL bulbs has been with the CFL size. Early CFL bulbs were large and cumbersome but more recent spiral designs especially the full spiral design gives a compact CFL which is often a prerequisite for modern lighting fixtures. The other major advancement in the CFL bulb is to contain the fluorescent spiral tube within a glass globe which means that the CFL can have a very fine aesthetic appearance.
The first commercial lamps were launched to the market by GE in 1958 and were Quartz Iodine Lamps using elemental iodine. The term halogen is a classification in the periodic table with the iodine and bromide elements used as the halogen in these products. It is the combination of the electrified tungsten filament and the iodine of bromide element which starts the “halogen cycle” which creates the light. Since the commercialisation of halogen bulbs, low voltage units have been used extensively in the automobile industry because they produce a very bright clear light which is ideal for vision. The emitted light has a higher colour temperature that the standard incandescent bulb which means the light from halogen bulbs is whiter. However, it is only more recently that the halogen technology has been advanced to allow the creation of commercial lamps for high voltage mains electricity for use in homes and commercial buildings. Also technological advancement now means that energy saving halogen bulbs are readily available which will save approximately 30% in energy over the traditional incandescent light bulb.
The origin of these lamps is from the Light Emitting Diode (LED) which was introduced into semi-conductor technology in 1962. In its earliest form they were low intensity red lights and as technology advanced the LED bulbs could emit light colours across the visible spectrum and in modern times with high intensity. They work by electrons combining with holes to release energy in the form of protons with different light colours dependent on the energy of the photons. It is only in very recent times that technology has advanced enough for LED bulbs to have high brightness. The high brightness lights were first demonstrated by Nakamura of the Nichia Corporation in the early 1990's and then the use of "YAG" phosphor coating was pioneered to produce white light LED bulbs. However the technology was still prohibitively high until a team at Cambridge University reported a process for growing gallium nitride LEDs on silicon which reduced the production costs of LED bulbs by 90%. These technological advancements now mean that highly efficient , environmental versions are commercially viable and represent the energy saving light bulb technology for the future.
