Fenix has some nice lights also,for work use I like a 18650 lithium battery model and prefer one without all the different modes like sos or the strobe,it get annoying,just a high mode and a low mode is good with me.
I couldn't agree more with this. I don't like multiply modes w/ strobe, etc. on flashlights. I do like a red light for night vision use though. A flashlight w/ high, low and red light is about the perfect model for me, especially a headlight.
