Strengths:    The light itself is pretty decent, and very bright on the highest setting. The button works well, and it stays fairly cool while you are riding. There is an optional flood lens available for $5 from Serfas (it supposedly used to be included). The charging time is pretty good at 3:00 hours for a full charge. The build quality is very good, as are all Serfas lights I have used.

Weaknesses:    The handlebar mount makes it all but unusable for trail use on anything rougher than smooth fire roads, or buff singletrack at moderate speeds. If you like to push the performance envelope, the light shakes like a wet dog with a bad case of the "DT's". It resembled a strobe light when sailing over rougher XC trails, which made it unusable for my purposes.

The light body is also somewhat heavy, which no doubt contributes to the shaking issue. This light appears to use the same mounts that are used on the predecessors in the Serfas line and could greatly benefit from a redesign.


Bottom Line:   
It would probably be great for commuting and path riding, but since this is a mountain biking site, I am reviewing it as a mountain biking light. I REALLY wanted to like this light, and agonized over returning it. I would have had to resort to some pretty dodgy ghetto-tech method(s) to get the mount to stop shaking and I could not justify having to do so with a brand new light that cost as much as this light does.

I wanted something that was easy to deal with and modifying the mount would not have been anything close to an elegant or simple solution. It wasn't just one part of the mount that had issues, there were three problem areas:

1) There was play in the actual slide interface at the furthest point the mount slides to.

2) The more movement happening between the spring tensioned swivel area of the mount and the body of the light.

3) And there was more slop between the part that wraps around the handlebar, and the bottom of the swivel part of the mount.

If I could have eliminated or reduced the slop in areas #1 and #3, I could have possibly have lived with the little bit in area #2, but the slop in all three areas combined was just too much to deal with. It's a shame that this light's usefulness is hobbled by an inferior handlebar mount as I think it would be excellent with a well designed mount.

It comes with a wall charger and cable, a handlebar mount as well as a helmet mount, and a cleaning cloth.
