What Are Leds?

Leds are light emitting diodes - in layman's terms they're like electrical one-way only valves that glow instead of getting hot when a lot of pressure is put through them.
They simply put out light (glowing photons) instead of heat like a normal diode on a PCB board.
These diodes are also then sealed in resin to make them shockproof and waterproof.
This is very different to the traditional filament bulbs that rely on a very thin piece of wire strung between two poles that burn very brightly when a current is passed through it.
The wire burns continuously whilst giving off quite a deal of wasted heat.
Glass filament bulbs are thin and also fragile which keeps an industry alive replacing light bulbs.
Advances from VHS to DVD get a lot more attention these days than cheaper, better lighting although the outdoor enthusiasts have recognize the incredible potential of Led lighting particularly in the form of headlamps and torches.
The difference at night time is incredible -you will see colors truly represented as they are seen during daytime - spiders and other insects eyes glowing back at you !
