The first thing that struck us about this light was the sheer weight of the battery - it was easily the heaviest of most we've tested.
However (and here's where you get to thinking about trade-offs), it also lasts longer, and if you're after this sort of power for more than three hours, the extra heft may well be worth it. You can see practically to Mars and the breadth is reasonable, but there's a definite centre spot that tends to burn out detail. And that's where you need to think about the sort of riding you'll be doing.
If you're planning on a fast pace in mainly straight lines, you'll be as happy as if you were in broad daylight. However, get to tricky terrain and you'll be wishing for a little more peripheral vision. Plus, the battery is really difficult to fix in one place, with a tendency for the cables to pull out at inopportune moments.
It's that combination of directional light and slightly diva-ish tendencies in the rough is making us save this one for dark commutes and winter road training. If you fancy trying one out for size, Lumicycle hire lights to test at Dusk til Dawn.
