leds?

hey,

so i was at a store last night and someone was talking about how the 1 watt and the 3 watt leds are the same, but you use a bigger driver on the 3 watt and in turn shorts the life span. is this true?

Leds really shouldnt be referred to in terms of wattage. They run at X volts at Y current. For example the cree XP-G leds run at a max of 1.5 amps at about 3.5 volts = 5.25 watts; however, they only run at about 3 volts at .35 amps = 1.05 watts.

do there is a diff between them? and it doesnt effect the life time?

Each model of led is different and has it's own optimal current for a longer useful life (although operating temperature probably plays a larger role in useful lives)

Read the data sheet for the led to determine it's optimal performance and useful life

ha there not much on it...it just didnt sound right when he said that and just wanted to know.

Has any of you guys heard of Auraled leds?
