I’m definitely interested in the lower temperatures, but not the 5000K - if the highest temperature was around 4000K I would probably get that too.
I’m happy with the C01R UI and NiMH support. I’m not interested in 10440 Li-ion support - I wouldn’t mind if it was an option but I wouldn’t want it to compromise NiMH support.
Interested if available in 4500K D220 and/or 3000K or below, would definitely pick up both. Don’t care about 10440 support, especially if the driver doesn’t have any stepdowns like the C01S.
A bit more textured/floodier optic vs the C01S is absolutely necessary though. E21A has tint shift through the beam in narrow, untextured TIRs.
