Thanks for all the effort, Match! Much appeciated. :beer:
Hi,
It's already been asked a couple fo times and I can't see a reply, but are you/would you consider testing a SST-90? The interest is huge because so many of the Chinese lights are under driven at 5-6As, where as the quailty units (Olight, VP2000, custom builds) hit out at 9-10 amps plus. It would be interesting though to see just how much difference it makes between the levels regarding lumens output. I shy away from buying the cheaper lights due to the amount of drive but if there is really little between, then maybe there is little reason not to try them.
I think he mentioned his power supply was maxed out w/ the sst-50 test
Thank you very much Match for the XR-E R2 results!
Was it an EZ900 or EZ1000 emitter?
I was inspired by Match's new guess-the-output contest...I plotted his XM-L test results along with Cree's data for T6 and U2 XM-Ls, accounting for thermal resistance. It's not 100% perfect [I made assumptions here and there for lack of data] but I was happy with how close the simulated data mimics the real deal (see chart 3; chart 2 refuses to cooperate). Data in bold font is overdriven territory-looks like Match got a high end T6!

Very Nice!
Not a diffrence the human eyethan pick up
agreed-I can *just* detect a difference in output comparing two of my Mags modded with T5 and T3 XM-Ls. Even then, I can't really account for how their tints (3C and 5A-ish) affect that perceived difference. Basically I had to find out if I could find out how well real life stacks up with Cree's data and vice-versa
Some of the images aren't visible, like XM-L and XP-G chart.
Can we have those back please?
Not sure why they disappeared, but I just fixed it.
What did you use to measure the lumens?
holy goddamn thats awesome
Need to get an XP-G2 to test now
Yeah, when I first saw it I was amazed. Now I'm considering trying to make one. :P
Really great work Match. I agree that the star is a likely bottleneck but entirely appropriate for these tests. I saw a nifty thermal image showing star vs reflow to copper. I also wonder if die size is a factor in the ability to tolerate overdrive.
Thanks for the nice comments guys.

I’ve been off the interwebs for a bit….are these released yet?
I got a preorder notice from Cutter a few weeks ago.
Thank you Match for this great tests, I always check you’re lumen readings when I want to make a new flashlight mod… Very useful.
