Hey guys just finished my new build and I was looking for some lumen/lux estimations based on spec’s. Thanks in advance for your calculations…

Convoy C8 host, OP reflector.
XM-L2 U2 1D on Noctigon
Direct driven- 3.34A @ tail cap
22AWG teflon wires, copper braid on both springs.

Also may be important, I used Kapton tape as an insulator instead of the white centering ring.

3.34A is roughly 1200-1250 lumens.

Emitter Test Results pt4: XML2, XP-E2, XP-G2, and Nichia219! (along with sinkpad tests)

Folks, Long time no see... Since most of you are now aware of my testing procedure, I'll be brief here. The following is a test of the Cree XML2 on a standard aluminum 20mm star, along with another xml2 mounted on a copper sinkpad. (member vestureofblood was kind enough to send me out these for testing). [image] Graphs speak louder than words, so here they are. The first one is the XML2 on a standard star, followed by a comparison graph between a standard aluminum star and a copper sink…
