Yes it does, and things like endurance etc suddenly become very important. Flashaholics in not used to power cuts gotta experience that once or twice in their lifetime to fully appreciate it, even it’s just a short 12-48 hours.

You’d soon find that small flashlights = small outputs, never mind the number of lumens it makes at 10 seconds, 30 seconds, 60 seconds, 120 seconds. The total surface area of the host makes a big difference, unless you could tailstand it in a jar of water that can cover till the driver portion of the head, that’s for your ceiling bounce or put a diffuser on top of it. Either that or you’d need to turn on at least 10 of your small lights for decent and useable outputs.
A few lumens isn’t terribly useful, though that’d do in an absolute SHTF situation in which one doesn’t have an alternate choice anyway.

I am not mentioning battery run time since I keep reading this and that BLFer having > 30 or even 100 cells in their collection. :smiling_imp:
And besides if you have juice from a solar setup, then power to you, it really slows down the “overall total discharge rate” of all the cells.
