Another member just converted a RMM level one modified Supfire M6 to red LEDs and an appropriate driver for me. It has the 7 level RMM user interface so output can be low enough for a good night vision preserving <1 lumen output to a very bright maximum red output for wild animal observing night use. Actually the lowest 2 or 3 levels are still good for night vision preservation. Surprised that RMM or someone else is not offering something similar as a standard light or a upgrade for some light.
I note that the OP’s converted lights are all relatively compact models while the M6 is huge in comparison and in high is now driving three red XP-E2 LEDs at 2.5 Amps each which should be about 1000 red Lumens out. Per the below link that is near maximum for these red LEDs.
Unless he sees this and wants to identify himself I will not identify the individual who volunteered to do the conversion but I would like to publicly thank him. I ended up with a unique light that fulfills multiple functions.
