These are rad! Got one on my keychain and one in my emergency/survival kit. The 1 lumen/45 lumen settings are great. 1 lumen for when I want to save the battery and 45 when I really want light. So far I've yet to run down my keychain light despite using it for a 20 minute walk on medium brightness.
My only gripe is that the bulb sticks out too far from the housing, so that if you hold it at hip level the light shines slightly into your eyes. They advertise the wide beam as a feature but I think it's a bug. The translucent plastic of the housing also leaks light through it slightly. So I have modified mine by creating a reflector with duct tape and titanium foil to help concentrate the light forward. A simple mod but I would like to see the next generation of these have a more focused beam out of the box. Still, a great tiny light.
JoomyI agree about the lack of a reflector and I was thinking of doing a similar mod. My plan was to use a little aluminum flashing tape with some black electrical tape.
If anyone has any other tips or ideas on this, please share.
JunkMailAluminium flashing would work but it bends very easily. I had some ti foil lying around and it's great because it's very resistant to bending/denting. I cut strips of black duct tape and cut them to shape to fit around the contours and the USB port. Fiddly, but didn't take too long.
JoomyI had never herd of Ti foil before and when you first mentioned it, I didn't think it would be reflective. I'll have to get my hands on some. Thanks for the info.
