I confess that my first thought so in the direction of "what can four small LEDs already generate for light" went - but as fits the saying "small but powerful"! I'm really impressed by the brightness, which I personally would like to see a little less flash LEDs. It is therefore - as promised in advertising - definitely for reading, even for long reading nights, because the Leuchtddauer is up to 9 hours when in doubt when fully charged.
I was really excited about this solar glass and I think I'll also give away one or the other no later than Christmas. With a recipient suitable for decoration, it is then not only an extraordinary, but also a very unique gift.
