I purchased this light and directly connected it to my truck battery to see the type of beam it projected. I aimed it a my shed wall which is white in color, I was shocked to see the output of this sorry #@% light!! The light looked like someone was holding their hand and fingers against it. There were streams of light shooting up and to the right, dark spots to the left and center, it just looked like a total mess! I am extremely disappointed to say the least. It seems to me that "Russ Wernimont" with his claimed 26 years of experience would have tested the the lights output before he put it on the market and attached his name to it. It appears to be more of a novelty item than a true headlight. if you are concerned about being able to see while riding at night you. SHOULD NOT PURCHASE this light. Sorry Mr Wernimont your light SUCKS!!!
