Just 10$? That sounds almost too good to be true. Are they of the same quality?
What do you mean with better batteries? Just ones that are of higher quality than the supplied one?
A light like this does seem useful for power outages and the likes. I don’t have a backup bag or anything, but now that you’re talking about it, I probably should. Maybe not for 72h, but something smaller can’t hurt. I guess I’ll start looking for some other equipment that could be of use.
And yes, the lowest setting is really good. According to the manual, it can last for almost 21 days. And it’s definitely useable at that brightness, too.
Oh I just saw that sale, that’s pretty cheap. Have fun with your light as well!
