Compared with the many 18650 rechargeable lights one can get for the same or lower price on the net...sorry, not that impressed.
Maybe they'd be good for pummeling a mugger?
Looks like they would be excellent household / emergency flashlights. Bike headlight ? ... not so much, for reasons already stated.
I consider a 2 aa cell flashlight (the classic Fenix LD-20 comes to mind) as just about the limit as far as length is concerned (the light was very "finicky" on the handlebars, the tilt tended to wander up and down on rough pavement ,also would bump the light sometimes when standing up to MOVE/accelerate out from intersections or standing while climbing steep hills). A 3 c cell light overall length would extend pretty far both in front of and behind the handle bars from the lights natural balance point plus the increased weight of the larger C cell would be more of a problem on less than smooth pavement.

The "Thing" with accidents is that they are so inconveniently unpredictable.

I had the smaller version of that. Its cheap for a reason. At leadt the 3aaa cell version lasted an hour if wrre lucky on a set of batteries. Honestly you are better off getting a couple of 18650 based lights. Good powet, small size.
I like them, they work well on the trike. Well balanced. cheap.
sams club has a similar light.
it seems like their lumen offerings increase every summer. 3 years ago i bought a package of their "250" lumen flash lights. i think they were made by "rocky mountain" or some such brand. in short, they were cheaply made. the rubber material covering the clicky switch was paper thin. the worst part about it was it was a "multi function" switch, meaning to turn if off and on you have to press the button g.d. 5 times. i hate that.
