Surprisingly Good

One of the most surprising things about this little light is how bright it gets. Build quality is amazing as well. Just what you would expect from Fenix!

John Crane
Fantastic little light

I love this light & use every night. Wear it around my neck on micro-cord. 3 lumens doesnt sound like much, but is the perfect amount when totally dark. Brighter settings are amazing.

Let there be light

Works great! Love the med setting. Very compact.

Great Little Light

Man I love these littles guys. I've the copper brown one for awhile now and have had no issues. I just recently purchased the green one to go with it. The anodizing on these things is great. The colors really stand out and look very nice. The light output, tint, and overall beam is superb for a lot of this size. The tent is just right. Not too cool and not too warm either. I do wish the UI operated a little differently. But that's okay. It's such a nice light it's hard to complain about a minor annoyance. I would definitely recommend these keychain lights. They would make fantastic Christmas presents for the wife, husband, college student, or just any flashlight enthusiast in general. They will definitely be impressed by these little E05r's . Happy flash lighting.
