This post is a summary of specs of all the important lights in this thread. Please expect numerous revisions because of several additions of more flash lights and more data, repeats of measurement, corrections of errors, etc. I am an amateur using hobbyist-grade equipment, pls set expectations accordingly.
Measurements I repeat measurements many times and make mistakes along the way so please don’t be surprised if you see changes or inconsistencies between posts from different timelines, such as early vs later posts.

External Temperature after 25 minute run-down from Turbo/Max brightness level, measured with IR gun pointing at the head area. Note that this is laying on plastic in a room without any cooling.
Convoy S21D —-> greater than 60° C
Convoy M21B —-> 59° C
Emisar D4V2 219b 4500k (with max thermal limit set to 55 C) —-> 49° C
Olight M2R Pro —->47° C
Sofirn SP36 BLF 4000k —->45° C
Convoy M21B w/ B35AM 4500k —->42° C
Both Convoy S21D and M21B have temperature regulation. It is set at 55 C in both lights. Emisar D4V2 also has temp regulation. The factory setting for upper thermal limit is 45 C, but I changed it in all my D4V2’s to 55 C.
