I've been doing a little bit of night riding lately and have used a couple different lights.
A few years ago I purchased a set of the round Magic Shine Style Chinese lights. They look very much like the light below, but if I'm not mistaken were listed as 1400 lumen.

I tried getting a wide angle lens, but it turned out to be a slightly smaller diameter than the lights I had and thus would not fit. I have however, loved the amount of light, but just wanted a wider pattern and maybe brighter if possible.
Recently I purchased a set of the new small dual lens lights, which are supposed to be a higher output than what I previously had. In comparison, the brightest setting on the new lights is about equal to the lowest setting on the old lights. However, the new lights are a much more dispersed pattern and make a very good flood light.

So I started searching for some new mounts and found these HOPE Universal mounts. I have yet to put them to the test, but first impressions are they fit the bill just right, well except that the included screw is to large a diameter and the one on the stock mount for the light is to short, requiring some rumaging for the right size and some washers to take up the extra space. On first glance I would deffinitly recommend these mounts with the expectation you'll need to hunt down the right screws.

I ran this same setup the other night and while I was dissapointed in the overall performance of the new lights, I think they will work very well in conjunction with my other lights.
