LED is the leading alternative to the traditional incandescent light bulb; or as we like to call them in the trade, lamps. LED stands for light emitting diode and is a semiconductor. As electrons pass through it they release energy as photons creating light. This makes them a solid state light and allows them to turn on instantly. No waiting for them to warm up! The way in which LEDs transfer energy means that only 5% is wasted as heat energy and 95% is transferred into light energy, making LEDs the most efficient option available. LEDs also require much less wattage to run, greatly reducing energy bills and environmental effects.
LEDs are upto 80% more efficient than CFLs and do not contain any of the toxic chemicals that CFL need to work; such as mercury and phosphor. Disposing of LEDs is very simple and they can even be recycled! LEDs have a longer life expectancy than the vast majority of lamps available, some claiming to run for several years. Environmentally they are the best product to choose as there is less demand for packaging and materials and less transportation. Teamed with their low energy requirements they create far less carbon emissions than any other bulb type.
Although the initial costs of LEDs seem expensive, the yearly savings on energy bills can be as much as 80%. The lifetime of an LED is around 25,000 hours in which time a 60W Incandescent would need to be replaced 20 times or more. Most household LEDs run at between 2W and 5W depending on which room they are in and how many lumens you may need. For comparison a 60W Incandescent gives off around 800 lumens of light. LEDs typically have a high CRI rating meaning they can successfully recreate the colour of natural or ideal light, in layman’s terms, it will be much easier to differentiate between black and navy socks!
