Lighting fixtures and bulbs containing LEDs (light emitting diodes) are growing in popularity which is causing more products to be produced and offered in the market to meet demand. Both residential and commercial lighting needs are improved by LED lighting for a wide variety of reasons. It is extremely energy efficient, puts off little heat, is compact in size, has a long performance life, is shock resistant, can be used with dimmers, is easily focused, operates in low temperatures, has no re-strike time, and doesn’t contain toxic chemicals (like fluorescent bulbs which contain mercury).
Fixtures made for LED lighting have also come a long way towards meeting the needs of both home and commercial needs. You can now get such fixtures as LED strip lights, bar lights, puck lights, dome lights, panel lights, flood lights, garden lights and more. These fixtures can accommodate such lighting purposes as under cabinet, entranceway, outdoor areas, work areas, accenting, and much more.
With LED lighting being deemed “the lighting source of the future”, it is good to know the following facts about this rapidly emerging light source.
Brightness – A standard incandescent bulb of 60 watts emits around 900 lumens of light. However, one high power Led only emits around 80 lumens, although that amount has doubled in past few years and should increase further. Therefore, it is necessary to group LEDs together in order to produce sufficient light.
Efficiency – The efficiency of any light source is measured according to lumens per watt (lumen/watt) which reflects the amount of light produced by a single unit of power. A traditional incandescent bulb produces between 10 and 18 lumens/watt and a common fluorescent bulb will emit between 35 and 60 lumens/watt. Warm white LEDs (those below 3200 Kelvin) emit 25-44 lumens/watt while cool white LEDs (those above 4000 Kelvin) produce between 47 and 64 lumens/watt, being the most efficient.
Lifespan – Realistically, LED bulbs last up to 60,000 hours under normal operating conditions and generally not the advertised rated life of 100,000 hours which is reached under controlled conditions. Unlike incandescent bulbs, LEDs do not burn out, but gradually grow dimmer until they are no longer useful as a light source. It is advised that LED light bulbs be replaced once they drop below 70% of their original light output.
Various Colors – One of the nice qualities of LED bulbs is that they come in a variety of colors which is excellent for creating different moods and effects within the home or business. You can buy LED bulbs in blue, red, amber and greed as well as standard white, although LEDs do not actually emit white light. The white color is created by applying a yellow phosphorous coating to a blue LED bulb.
Safety – LEDs are safer than their lighting counterparts. LEDs don’t emit infrared radiation as an incandescent bulb does and they don’t produce ultraviolet radiation (UV) like that of a fluorescent bulb. LEDs also emit much less heat and contain no dangerous gasses or chemicals which can harm the environment.
