The Shining Beam S-Mini is small and light and puts out plenty of light with very good run times .

It has 3 useful modes (hi, med, low), last mode memory and runs on 18650 batteries (1). I'd get a couple of Redline or AW (i.e., Panasonic re-branded) 3100ma or 2900ma batteries (candlepowerforum.com market page has some,...or you can find them on ebay) .

The light you are looking at is probably a fine light, ....but I think its a little heavy and would be harder to work with . A heavier light on the helmet makes the helmet tip to the back or front and is noticeable to the neck strain,....and if mounted on the bars, the heavier light is harder to lock in a position .



TwoFish Lock-block works well for mounting the light to either the bars or helmet ..., 4Sevens.com sells them,...ebay, Amazon and others ...
