BLF-member CRX has made a database with a lot of leds and other stuff, and he is keeping it up-to-date (wow, the XHP50/70 tests that I posted last week are already added!), the most widely used emitters are in there:
Gotcha, and fair enough. Clearly I either didn’t know they’d updated the datasheet with S2 or I forgot. Actually I now see that the latest XP- series B/L datasheet has S3 listed! But no order codes for S3.
I bought a few XPG2 S2 1D and XPG2 S3 3C from ios which are very impressive, as rated: S2 558-595 lumen at 1.5amp and the S3 595-625 lumen at 1.5amp. Almost catching the old xml output. The latest xml2s and xpls now put out 1200+ lumen at 3amp . I put a xpg2 s2 1d[ dedomed] in my sunwayman t20cs for [originally xml 650lmn] 600 otf lumen and 55kcd and my ea4 improved massively at 1100 otf lumen and 32kcd[XPL V6 2C] both stock drivers on copper noctigons. If you have any older lights these new gen crees offer an easy, effective [ some led swaps are harder than others] upgrade to an old favourite.
