Again match your work is invaluable. Thanks for the huge effort doing this for us. My only concern though is that no one will build a light like we have before. I'm doing a mod on a particular flashlight at the moment that I thought was all planned out. XM-L2 on a copper star on a beefy copper pill in a large ally housing running a 5 amp buck boost driver. Do I now have to get a 9 amp driver to run the XM-L2 at its peak? Bugger, it never ends. Cheers and thanks again.
PS. Maybe I could use the 5 amp driver on a killer XP-G2 build?
These types of post are one of the reasons I check forums. Provides such a wealth of information! You’ve inspired me to build an integrating sphere once I find the time.
Thanks a lot for all of your work for this forum and it members Match. Your contributions stand second to none and are head and shoulders above anything I've managed to put forward.
A friend just pointed this out to me: Lightmall are now using these graphs on their XM-L2 product page and claiming “1770 lumens” on some of their XM-L2 torches.
They prove they can't understand the CREE datasheets too much, "maximum driver current 6200mA". They neither specify the bin of the XM-L2, they don't understand that either.
Actually there are many stores that simply copy the other store and I am sure they don't even understand what they sell, but since it's popular on the forums they got to sell it.
since they don’t point out theirs is not a sinkpad (or even mentioning the word sinkpad or massive amounts of heatsinking), i can imagine some non forum person thinking they can buy this and put 6200mA into it then seeing the puff of smoke or potential fire
