Really difficult.. the test say 996,8 but in a flashlight are 1145 otf... Let's say 1029 (was 1001 but i mod it because someone already choose it)!
Thanks for this "game"!
1,141.03 lumens
Folks,
I'm noticing some possible confusion here. What I've done was test a bare cree xm-l directly bonded to a big chunk of copper, which was attached to my 25lb aluminum test block. This test was exactly like all the other emitter tests I've performed, except I've eliminated the pcb (star). Just the emitter...no optics, no collector, no worries
Hope that helps.
Sorry Davx but I picked that # in post 59.
[Edited] Is it a T6 or a U2 or....
My spreadsheet says that your old setup had a thermal resistance of 5.7
The new setup Has a more direct connection to the die so I would guess a Resistance of 5.5 . A T6 should give....... 1000.7 lumens

My bride is a big fan of that show, so I got a pretty good laugh from that. Thanks.
1013 is my guess.
NO BASE/STAR !

1338, all-in!
This post is like a random number generator lol :D
Ok, so here is the number, 1010 generated by me.
Thanks Match anyway!

That's easy: Take in account the old resistance of 5.7 ... uncertainty of LED (T6 + U2) / 2 ... 6'416mA at max Flux ... old star vloume Pi*(0.02m)^2*0.03m ...
=1'268 lumens - no need to gess (and 100 lumens mote than the SST 50 on star)
Edit - 1023 woot
