Love the size, love the modes, don't like the way it wobbles when tailstanding, tired of it turning on in my pocket and I'm tired of lubing/cleaning it every week now to keep the contact wire happy!
At least three modes, 1 lumen of so for low, 100 or more for high around 30 for normal mode.
CR123 AND AA would be best, but I'll go either way on battery. MUST tailstand! I like the size of the RA and would like to stay in that range, so single cell, unless it's CR123 and AA, I'd take two AA's for that trade off. Must be WARM! Warmer the better! I upgraded my E21 with a High CRI XP-G and the RA looks grenish/blue compared to that now!
Lots of wants and needs in such a small package, maybe it's no wonder I'm getting so confused!
