That dealer has some interesting offerings - I saw a T6 emitter using 2x18650 for 34.80 - but as you say - beware.

I rode Friday night with a Solarforce M8 - very deep reflector - slightly tighter flood than a TK41 - and after comparing the "eye effects" upon using a flood light and a spot beam I have concluded there simply is no best "light." The situation defines the lighting need.

One thing is obvious though - a flood is the best way to assure coverage on a trail. And a "spot" is the only way to get "throw" on a long way down the road.

Hence - I'll be riding with both........
