Thanks,
the 1.2A current should be constant with 2xCR123/RCR123
Many manufacturers exceeds the recommended current, but that doesn't mean that it is the good thing Current to the LED in T100C2 should be 850mA...
The Quark lights use 700ma for their AA^2, 123, and 990ma for Q123^2
I know but as I wrote above I think the junction temperature may be much more important than the current by itself. I don't know about the phosphor layer but if cooled the semiconductor part could usually be pretty tolerant to the currents higher than specified.
In flashlights there is no active cooling - 990mA may be 40% higher than specified with the perfect thermal design but may as well turn out to be 100% higher if the LED junction temperature raises too much. That's why I don't think one can for example compare a Quark with 990mA and an EagleTac with 850mA and given only these information be sure which of them is more abusive to the LED. I think it may be possible to check the LED temperature by measuring if and how much the output gets lower after the lights heats up.
4sevens accused Eagletac of stealing their marketing material and illegally copying the M20 design.
Sorry to pile on EagleTac, but I noticed many instances of their documentation (warrenty card, user manual, etc) is taken word-for-word from Surefire's user manuals. Maybe they are innovative in some respects, but dang EagleTac. It all almost makes me regret my T20C2 purchase. :sigh:
