I'm guessing that it's not suitable for LED flashlight (e.g. L1D) unless you have a really small (really dim) led. I'm no expert; I don't know what happen if you try to discharge it too quickly; I'm guessing that it won't be good.
It's usually sold online; I think the main consumers are electronic manufacturers who need long-term (e.g. 10 years) continuous power (e.g. to retain RAM).
