Best EDC Light!
When I went to the post office today to pick up my SC52, to be honest, I wasn't expecting much, I thought: well...this will just be like the rest of my EDC lights, small and not great. But, soon as I opened the little brown box and got out the light, I popped in a 14500 and was literally, BLOWN AWAY! I highly recommend this to anybody looking for the ultimate EDC light. 500 Lumens on a 14500 and 280 lumens on an Eneloop, and a max run time of over a month. What more can you ask for? Buy now! :)

My most impressive flashlight
280L from one AA, 500L from a 14500 li-ion. No other torch can do that! Tiny, solid, great beam and switch, UI allows turning on in low, med, or hi, depending on how you click. Improvements over SC51: brighter, more settings, accepts 14500 battery, and battery level indicator. Removed unneeded clip - fits anywhere. Filed down sharp mounting base corners.

This flashlight (SC52) is the best EDC I ever had, I even preordered a SC52w 3 days after getting it. High is very impressive for a single AA and low is really low. UI needs getting used to it but when you get it it is surprisingly intuitive and efficient. I give it 4 stars and not 5 because I got mine with a scratched pocket clip. I have asked for a replacement clip with my SC52w order. We'll see how it goes.

Pocket rocket
High output with Eneloops and >440 lm with 14500 li-io. Not too blueish tint for a cool white light, beam is smooth enough but not perfect. Would by again! Full review in german Taschenlampen-forum

Impressive light
The SC-52 impresses on all fronts. It looks great, feels great and the output from such a small light with a single AA is amazing. The beam is a nice balance between spot and flood. UI is both flexible and easy to use. Battery run times are also very impressive. So much from a single AA!
