Led lights vs normal lights

A Light Emitting Diode (LED) is basically a diode that lights.

Since it is a diode, it is considered solid state lighting. This means that compared to halogens, it doesn't have a filament that bruns out. Therefore it lasts much much longer. How much longer? Easily 50x.

Compared to halogens which use a lot of power to heat up a filament until it glows, LEDs are semiconductors that emit light when current passes through. This means it uses much less power. How much less? Over 90% less.

Since it uses much less power, it also produces much less heat.

I can go on about its benefits, but i'll stop there. I'll mention one typical drawback -- cost.

I am a bit of a lighting guy as I am involved in this industry. You can also use LED for home and office lighting. *hint hint* Power savings, anyone? This is somewhat of a passion. Any more questions, PM me.

your suggestions please...

noong nag-sale sa Concorde yan ang binili kong brand ng LED para sa trunk, almost a year na wala pang pundi.

If I may add, the power supply and overall design has a lot to do with an LED's useful life. Too much current or if heat is not dissipated properly (for high-power LEDs), lifetime is drastically reduced. Also consider that the 50,000 hrs life was determined under ideal conditions. High power LEDs are usually driven by a current that is slightly higher than typical (how high is again dependent on the design) and would usually last only a fraction of the advertised 50k hrs.

thanks for sharing your knowledge all...

LEDs have definitely come a long way,- from mere logic signals in electronic circuits, to displays, and now lighting solutions.....

medyo may kamahalan nga lang elevo/carstethics brands being sold sa blade/concorde... meron ako binibilhan 150pesos lang 12led viking brand galing china. ok naman walang problema.
