i would never give Li-ion to non flashaholic person…simply because if he or she does anything stupid with it i don’t want to feel guilty about it…
Sure. :)
But if the alternatives are:
- 2 x CR123A lithium primaries (no protection circuit)
or
- 1 x 18650 rechargeable li-ion (with protection circuit)
..so I would say that the second one (1x18650) is safer.
Unless it’s a cheap Chinese 18650 and protection, and a cheap Chinese charger. Anything is possible, but not that likely.
I went back and looked for that. All I could find was his review of the 4.35V model. I did find another review by Overclocker that seemed to indicate Version 2 of that charger was acceptible. There was some concern from one member who noticed his was charging to 4.25V. On the one that I have been using for about 8 months, it is still terminating at 1.19V-1.2V exactly, even if the cell is left in it for a number of additional hours. Looks like I may have gotten lucky, or perhaps V2 of the charger is improved.
Leaving the battery for a couple hours after termination is not good enough, i assume it will stay on the charger for days, as a failsafe i have to assume even months it may get forgotten on the charger
No significant other or children, but i can’t give a loaded gun to a child (figuratively) and wash my hands of it, which is why i like the NiMH option if it has the output needed.
in canada why not buy

4 AA ..well made ..beautiful beam with lots of throw ,no funky pwm,spectacularneutral white 4b tint and much better color renditioning . 4 well thought out modes , forward clicky and a seperate button for changing modes ,a strobe that is just horrid it is the most siezure inducing strobe I've ever seen .
Given that your mate is likely to break/blow up/hurt themselves why not get a dedicated work light AA powered but cheaper than Li-Ion + charger by a long way but most of all safer.
It doesn’t have enough lumens, about 700 or more to fill the task of worklight, but the starry light does look a lot like that fenix, perhaps thats what its a clone of 8)
@8steve88 Its been my experience those 5mm led lights are well under 50 lumens
Wasn’t sure they wouldn’t stare at the light too long and damage themselves. :bigsmile:
No more so with LED vs incandescent or CFL 
LiFePO4’s are supposed to be a lot safer, although they terminate at about 3.7V, and generally have less capacity. Would not be as bright as a regular Lion, but will your friend notice the difference? I have a few and give them to my wife to use in flashlights I lend to her.
the price went up, its not quite bright enough and brightness falls as soon as you hit the on switch, if it were i would sell him my cyclone C88 which seems to be the predecessor to that light, 3AA, XM-L U2, same driver, if it were 4AA i would definitely go for it
I’m personally thinking that a flashlight is not a good idea for this task anyways (not just for this fellow), an hour of runtime is not enough, and i’ve been doing some basement work with my convoy s2 on medium, and when the battery dies 1.5hr later the one on the charger is still not ready (1000mA ML-102 charger)
Edit:
@Metalophile i was thinking i would go with a lower drive current because he won’t notice and reduced heat production for a small head flashlight is a bonus for a non flashaholic. In this case the biggest things are cost and safety, i have given a few lights as gifts so far but they have been 1AA lights, if people could not handle alkaline then they would be injured long before i came along, and the batteries are easy to get, and they can upgrade to eneloop at their convenience if ever. In this case 100-150 lumens are insufficient, otherwise a klarus p1a as a flashlight for general use is hard to beat.
