Thanks for the update on the 17mm boost driver.

I don’t have one to try, does UT01 work on a flat top?

Jaxman has good tints but tend to use XPG’s instead of XPL’s, and they don’t like to drive their small lights too hard. So they end up wanting power modded. I think the E3 would be a much better overall light if it had it’s current output levels, plus an added high/turbo level of 500-700lm
