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. =)

Only a few more hours to guess and/or modify your answer!  Asn an aside, I can't believe I forgot to mention that the xm-l was a T6....my bad.

Some pretty good guesses.....others have kind of made me scratch my head in confusion a bit....

Last minute hint:  If the number you've guessed isn't 4 digits long, you may want to change it.

I had 999, but since your clue says four digits... my instinct is to say 999.9 because I think you are clever enough to not mention the need for a decimal.  That's what I would do.   J)

But then again...

Final answer 1313.  I didn't take the time to go back through all the posts to see if that was taken, if it was, sorry, please ignore.

Don't be confused, my Username has been changed from "Cone" to "T.H.Cone".  I'm still the same clown.

Thanks for this, Match!

If only I'd been born dyslexic and swapped the 0 and 5!

Thanks for the contest, and more importantly the data, Match.

THANKS!  Awesome testing Match, and incredibly impressive results.  I have to admit that I have a little bit of experience with REALLY well heat-sunk LED emitters, but I am still a bit surprised that you were able to get those numbers out of an XM-L; I thought I was a bit high in my guess.  Really awesome!

As for the prize, it's a beauty!  Can't say thank you enough!

Next up: XM-L Soldered to a copper slug with the slug bonded to a TEC Smile  Can't wait for that guessing game Smile
(hint: I have a bit of experience with that as well..hehe)

I am currently extremely busy with work. Please do not expect a response from me quickly. I will be dropping in as time permits, but the amount of time I can dedicate to responding to topics and PMs is very limited.

Congratulation to PilotPTK, prize is very nice! Testing directly to copper mounted xml is interesting itself and this contest made it more attractive, thanks Match!

Why not just pour tons of liquid nitrogen (or even liquid helium) on the damn thing, like some PC hardware overclockers do? Big Smile

What is a TEC?

Thermoelectric current device.

As a very short explanation - it "pumps" heat from one side to another, resulting in substantial temperature difference between them.

So, for example, if you manage to keep one side of TEC at 30°C, the other side may be as cool as -20°C.

http://en.wikipedia.org/wiki/Thermoelectric_cooling - here's more detailed explanation.

Wow, that's one nice prize! I wish I'd gone with my spur of the moment urge to put down 1500 now, instead of going for the 'sensible option'..

 

Anyway, congratulations PilotPTK. I hope you enjoy your prize, it really is something special.
