I already have JetBeam BA20, which has XP-G, so Im kind of looking for something with even better throw, its not a bad for the money I paid, but something cheap is into consideration as well, if I cant find E21/E40 for very cheap :D!
So you bought, right :D?
Tell us you did :D!
I dont expect much from that light, but if its really Cree then it might be worth it, or might not, depending on beam pattern and mA draw.
Better throw - bigger head - smaller emitter
I can’t stop suggesting ITP SA series! (SA2 model for 2xAA config. <$40 for sure ). Initially, SA series were shipped with R2 emitter. If you can find it - it may out throw BA20.
