It is amazing what lighting we can get nowadays and for so little western currency, from the RoC.
What battery size do those take?
I have a little mini head light for walking that does very well on little 2032 button batteries..
But I actually hate to use any
non rechargeable batteries.
Also anything with really big batteries seems to use them up
just as fast, by taking advantage of their large capacity and being as immensely bright as possible, which can be useful at times too, of course.
It we could just as easily get the best of both.. by taking the middle step where we have some added capacity we could have some added costs and some added some added safety. Its not all one or the other!
Batteries don't perform as well when they're very cold.
I suppose it's easier to warm up a small light in your pocket or swap between two lights, one in pocket while other is on handlebar, so there's always a warm battery... Not that I do, because being "old and wise"
I stay indoors or close to home if it's cold lol, and I don't miss the starry skies too much really.
