The Swedish-designed Bookman lights (thanks
Smartech) are considered pretty much the best of their kind: they’re high-quality, slim, easy to mount and surprisingly bright for their size. The
Curve Light goes a step further—it’s more like a super-bike light. This little weather-resistant thing has got a brightness of up to 220 lumens and a possible run-time of up to 70 hours. Both of which are
insane.
