About a week ago, a friend of mine who is a SureFire fanatic, did a modification for me, of an old L1 bezel he had in a used parts box. His original bezel had a 1 watt Luxeon with a Batwing configuration. He replaced it with a new 3 watt Luxeon with a Lambertian configuration.......I somehow forgot to ask him the bin rating. My measurements of this bezel, taken with my ammeter across the battery negative and the body of the light, were 850mA at 3.0V.
In the page below, the spec for this LED is 65 lumens @ 3.70V and 700mA, or 80 lumens @ 3.90V and 1000mA. When I compare the output of my original bezel with the bezel he modified, I see a slight increase in brightness and a very white beam, instead of the slightly purple one indicative of the 1 watt Luxeon used in the L1. The L1 is stated to emit about 20 lumens in the high beam. Why isn't the output of the new bezel, similar to the figures on the Luxeon webpage below?

I know that there is some circuitry trick preventing the output from reaching 65 lumens, but I don't know what that is or why this was done? Can anybody clear this up for me?
