I guess you could say I am a lightoholic, knifeoholic, gearoholic, etc. If you want to be nasty, I guess you could say I am a light whore, knife whore, gear whore, etc... Just not a man whore. (Deuce Bigalow is super funny) Actually, I have a lot of different brands of lights. Fenix is one of them. I find Fenix to be reliable and reasonably priced. So even though my fatbike came with a headlight, I got a better one. The stock one is a piddling 200-300 lumens, which is ok if that is all you have. But it does not light up as far or as wide. My plan is to leave it on and aim it down maybe 30 - 45 degrees. The Fenix light is much brighter, and has a dual beam technology. Two bulbs and reflectors. One aimed for throw and the other for a smooth wide angle beam. Here is my fatbike parked in its locked garage. Turned the light on for the picture. Light on turbo at 800 lumens. It has a max of 1600 lumens. I traded a little brightness for a display that shows remaining runtime. Light aimed at a tree about 60 feet away on the 800 lumen mode. Didn't take a base line shot. The tree was totally dark. It is lit up pretty nicely. So the headlight makes it easy to see and be seen. Halo belt on the back for night rides.
