"…it now matches or surpasses most big bar lights for picking out detail at distance on the trail. It's still plenty bright enough for helmet use on technical trails in the medium setting too...super powerful expandable helmet/race light for weight watchers."

"The beam pattern is consistent and reasonably well spread. It's stronger down the middle, but there is enough diffusion to cover a wide angle out to the sides and over the front wheel."

"Until this product was available, helmet light only levels of brightness were the sole prevail of lights with cables dangling from the back of your head. The excellent beam pattern developed by Exposure coupled with levels of brightness previously only available with bar mounted lights, make this the essential partner to the 6-Pack for the ultimate race day setup for me."
