1013 is my guess.
NO BASE/STAR !
1400
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!
1109
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
My bad! I've already mod it! Sorry
Iām curious, how do u get power to and from the led ?
Gentlemen,
After a very frustrating few hours, I have just finished testing the output of everyones favorite Cree XM-L while directly mounted to copper, similar to this. In celebration of this (whoo-hoo!), I've decided to do a giveaway of sorts.
Here's the deal!
- Post below your best guess as to the max lumen output achieved during the test. For reference, the testing was conducted exactly as my other emitter tests as found here. (big block -o- copper/alum, regulated power supply, Fluke RTD temp and amp monitoring, 30sec stable, yadda yadda yadda....)
- No, you do not get to know what current level the testing stopped at. But, looking at the data from the previous xml, mc-e, and sst-50 tests may give you an idea.
-Post as often as you like, but one guess only. If you change your mind before the contest is over, please re-edit your first "guess" post.
- Contest to end next Sunday night (5/20) when I finally make a new post of the xm-l testing results. Then everyone gets to see who was closest. Yes, this means I get to sit on this delicious data for a whole week! muhahahaha....
Here's the Prize!
A long time ago I was sent a light by one heck of a great member here. I don't want to name any names, but it rhymes with "MacktheStripper" . The intent was for me to mod it, then use it in a givaway of some sorts similar in concept to this one. This drawing here is my attempt to make good on this deal.
The bugger of it is, that little 3xAAA incan light has been an albatross around my neck...for I have a hard time seeing any potential with it (too short for 18650, to fat for a single eneloop, and the host material has more in common with Playdough than any actual known metal). So, while the rest of you are feverishly speculating lumens, I'm going to try my damnedest to make that little light special for the prize.
Since I never roll without a back-up plan I cowardly reserve the right to offer up another of my mods in place of the afformentioned light . Depending on how frustrated this comming week is and the nearest proximity of a ball-peen hammer, this may end up happening. Regardless, I'll post a shot or two of the light and any progress (or lack thereof) made.
Time to put on your Thinking Caps and start guessing!
Best of luck,
-Match
hmmm..... 1220. My guess...
My guess would be --- 1207
@cheaplite: He soldered to the tiny silver squares you can see.
When will we find out?
1414.
I'm Curious about the result :)
Great idea for a giveaway. But I have no idea, not familiar with lumens output..... I will post my guess later. Maybe I will just get the 10 most number guessed and take the median as my answer. =)
1156
1008.3bhp
1435
800 lumens.
