115 lumen > 144 lumen ain't shinola...you would need 230 lumen before your eyes could make your mouth say >>>> ""oh yeahhh..""
I'd stick with the AA format....aaa X3 Nay.
Firstly, xpe in this reflector has way better throw than the coleman max xre. I never liked the xre, ringy and need really special reflectors to throw (contrary to what I read here). Also, tint is improved (on single light, I purchased). My point is a big difference in usefulness for detail work and useful lux runtime. (The degree of beam spread is subject to laws of inverse square for lux. Lux is needed to see detail. So, a small increase of flood usually means a huge drop in useful detail runtime.) As a result, I have been more pleased with rebels, and found few cree lights that could throw as well, be as useful as long, as my lux 1 army of headlamps (brinkman/garrity). Though, a few well matched reflectors/cree (xrc&xre) of mine, will kick the pants off the lux1's on throw. (especially the walmart x-rc).
Secondly, I will report a huge drop in brightness after roughly (gut timed) an hour use with 3 rechargeables AAA. After this hour, the brightness was on par with the Remington low (20 hour) setting.
It also is too heavy for a strap on head light, and single drive mode often too bright for task. So, I guess I must break out a hack saw, solder, wires, amazing goop, wires, variable pot, AA battery holder, and elastic. Should make a good 3 AA headlamp with 9 hours useful run time. The trick is to make the wires and solder joints indestructible, when the weak link is in the battery holders sold to us.
In the end, my entire satisfaction with this light will be determined when I find out current ( a fresh cell acceptable current for me is <300 for 3 AA format) or bin of the emitter. It could be a q5 to r3 bin. If r3, and I find an indestructible headlamp mod, I will buy more.
