The perfect light for environments where you need to be seen, but don't particularly have to light up the road ahead of you. There are modes for just about every style and circumstance, the 40 lumens being most effective in low light/after dark hours. It's a well designed light, every aspect is just enough and no more, making the unit seem light and compact without being fragile or problem prone. I like the built in USB tab - no charging lead required - and the quick access magnetic catch. My local branch organised the last of these for me from around the country, in good time and with their consistently dependable service. If they come back in stock, give them a look.
