Beam output is powerful too, with a broad fuzzy 'smile' and separate mid fill strip that stretches a decent length down the road for confident speed even on unknown roads. There's absolutely no mid distance peripheral though, so we occasionally got spooked by roadside animals or side turns appearing at the last second.
A helmet mount is included if that really bothers you, and the big overkill thumbscrew mount is secure on your bars as long as they’re round. Plentiful power means battery life is short for weight at full beam, but it’s communicated clearly by the main button and a warning light that comes on very early. The battery is also replaceable so you can buy a spare to extend run times if you want.
