LED Lighting

LED lamps have been around for many years, typically used in gadgets such as digital clocks, TV remotes and as Christmas lights. They contain none of the harmful chemicals such as mercury which reside within CFLs, are much smaller in size than their CFL counterparts, can last for over 20 years of use and offer considerable energy savings on alternative forms of lighting

There are a wide range of LED replacement lamps available. In most instances it is as simple as changing a lamp for an LED alternative. In other cases it is a matter of changing some of the control gear within a fitting to allow for the upgrade.

Key Facts

LED lighting offers a wide range of benefits compared to conventional lighting technology:

LED lamps use 90% less energy than incandescent bulbs

LEDs can last for 25-30 years, dependent on use

LEDs reach full brightness quickly at start-up, no waiting for the lamp to warm up

LED lamps run at much cooler temperatures so have a reduced fire risk than traditional Halogen lamps.

The Science Behind LED Lighting

LED stands for light-emitting diode, and LED lamps differ from traditional incandescent and compact-fluorescent lamps (CFL – energy saving lamp) in the way they produce the light.

LEDs produce light through the use of semi-conductors as opposed to a tungsten filament (in the case of incandescent) or a mercury-vapour discharge (as in CFL). In turn this allows LED lamps to give a better efficiency as there are fewer losses involved in generating the visible light.

A standard incandescent lamp gives out approximately 14 Lumens/Watt, a CFL is rated at approximately 80 Lumens/Watt and an LED is above 80 Lumens/Watt with some now giving an efficiency of up to 100 Lumens/Watt.
