An LED I'm looking at has various specs listed that I can't make heads nor tails of. It is listed as a "3W LED" supporting a 2.5V minimum and 3.6V voltage. However, "Forward voltage" is listed as 3.4V-3.6V. Which makes me wonder what the 2.5V minimum means.
Also, it lists "Forward current" as "350mA@1W 700mA@3W". Now, if I take those values I get respectively 1W/0.35A = 2.85V and 3W/0,7A = 4.28V - totally different ranges than listed under the supported voltages. Besides, I would imagine that a 3W LED running at 3.6V would have a forward current of 833mA. Why are they listing two of them?
Is this just a mistake on the seller's specifications or am I missing something?
