The light readings showed the Voyager 3.0 to be surprisingly bright, but only in a very narrow portion of the beam.
Given both this fact and the distance by which the LED is recessed into the lens, the light's side-on visibility suffers. It is nowhere near as visible as the Quadrant - which comes in a two-pack for the same money.
The beam from the Voyager is just enough to ride with on dark roads, but if you're travelling at any kind of speed its limited projection soon comes into play and you find yourself riding beyond the scope of the light. Running on four AAA batteries it gave 18 hours of constant light, which is two hours less than claimed. This isn't a bad light by any means, but it's not bright enough to ride with at speed, and not as visible as other comparable lights.
