You might be a good candidate for a tint ramping light from Hank

There is also the new S21F from Convoy. There has been a bunch of discussion here about it.

Convoy S21D w/ legendary Nichia 219b - Review & comparison w/ Nichia 519a, E21a & other lights with Nichia LEDs incl. Emisar D4V2, Convoy S21F. (Summary & measurements on P. 1)

This post is a summary of specs of all the important lights in this thread. There will be numerous revisions because of additions, repeat measurements changing results, mistakes (mine), improved knowledge, changing opinions. Specs from Simon: Lens Multiple TIR choices: 60° Bead, 30 Bead, 10 Bead, 10 Clear (available from Simon, or possibly as gift at time of purchase). See comparison and beamshot discussion HERE Driver S21D: 8A Buck (first release, like mine, >90% efficiency - more than FET)…
