First let me say Great Thread,this is one of the best reading and informative threads to come through CPF in a while.I have followed it with high interest.
I built a homemade lightbox a year or so ago,and have been very pleased with the results,though it was not nearly as impressive.It was put together very quickly and rather sloppily because I was unsure of the outcome,and didnt want to spend too much time if it didnt work.
I have mine very close,within 5%-7%,I believe.SSC P4 USWOH's from Fred
have all measured 240-250 @ 1000ma.A Surefire 6PL starts out around 100,but drops off after a while,which I think is correct because if you look at Chevro's runtime chart,it drops off after about 1/2 hour and remains fairly constant for the life of the batteries.
May I make a suggestion?
MrGman,I am assuming you have a CC power supply near the IS you have access to...
precisionworks,do you have access to one?The reason I ask is this,I would be very happy,if you guys were willing,to put together a few bare emitters on heatsinks to wire up and test output.I could cutdown a Mag into 5 or 6in sections and mount the LED's on H22A heatsinks,with a Deans plug or similar coming out the back to make the connections quickly.The LED's would be a Cree XRE R2,SSC P4 USWOH and P7 CSXPI.Also,maybe a well regulated torch.If you guys dont want to go through the hassle I understand.Even passing around a well regulated light that MrGman had tested would be extremely helpful.
Thanks,
Michael
