Is your semiconductor producing narrow-spectrum light?

I beg your pardon!

No, Seriously. This is not a euphemism. I am talking about LEDs (light emitting diodes). You probably have a bunch of these beauties in your home already and may not have even pondered about them…until now.

People put them in everything from remote controls and smart phones to night vision goggles and even traffic lights. Folks are introducing new uses for LEDs all the time.

So what’s the big deal? They use very little energy and can outlast a compact fluorescent bulb tenfold and can match the brightness of a traditional bulb. They also come in colors other than red (originally, they all were red).

Chances are good that you’ll find an LED alternative for lighting at many major home stores, etc. Why just recently I was online shopping for floodlights and “bam”; there were several LED versions available.
