I’ve finally received the shipment of Zebralight SC51 flashlights that’s been on order for awhile. And I love this light!. I’ve been running one on a Eneloop AA rechargeable and the output is amazing. The high is 200 lumens, the low is 0.2 lumens, and the levels in between seem to be just right. You can also turn the light on in either high mode or low mode, your choice, every time. Throw is very good for a light this size and of course flood is good as well. I have not tried the headband but it looks like it should work quite well. The first picture compares this light with the 4Sevens Mini AA and the Jetbeam Jet-I Pro. It’s not much bigger than the Mini AA. With the clip on this light, it literally disappears in your pocket.
