Poor mounting bracket design
300 Lumens isn't that much - a ‘to be seen’ rather than a ‘to see by’ light
Would be totally out of its depth off-road

I bought this light primarily for my (fast dark and wet) urban commute; I also hoped that it might be sufficient for a little light off-roading, but is seems that was a bit too much to ask of a 300 lumen light. I’ll admit, I didn’t really have a clear concept of just how much light a lumen represents. For commuting, the 300 lumen ‘blast’ mode is fine, it doesn’t exactly turn night into day but so far it seems to be enough for other traffic to notice me. On well-lit streets, this light doesn’t really make much difference to how far, or how much, you can see; road signs do stand out though. On un-lit roads, it is just about sufficient to see where you are going, but no more. I haven’t even bothered trying it off-road.

The integrated re-chargeable battery is neat and seems to last reasonably well, the battery level indicator lights in the switch are also a nice touch.

Whilst I haven’t yet had it long, build quality of the light appears excellent; it feels as if it will last a long time providing it doesn’t escape from the mounting bracket. I have read many tails of the light jumping out from its mounting bracket and getting lost, I can see exactly how this may happen so have modified by bracket with the addition of a pair of rubber O-rings. The O-rings are looped around the bracket and the lamp slides inside them; this prevents the light moving vertically up out of the bracket and provides downwards pressure, ensuring it can’t slide fore/aft either.

So in summary; if you are an urban commuter and want a light weight and easy to re-charge light that doesn’t cost silly money then I’d say go for it (providing you modify the bracket). If you want a light that will intimidate other traffic, work off-road or turn night into day, look elsewhere.
