I just picked one up this week. Ordered an extra battery and some extra glass lenses (no charge). I turned one of the spare lenses into a diffuser for my video work by going to a Michael's craft store and buying some glass etching solution. You wipe in on the glass, let it sit a minute, and then wash it off with water...creates a frosted lens which smoothes out the light pattern. The 75W light is about the same size as my Oracle 35W light, and has a "whiter" light color. The head is a little smaller than the Oracle. I am pretty happy with it so far. Need to run it in a little. You can adjust the beam as mentioned previously, though I don't think it is designed for "focusing". Now all I need is to find a padded sleeve for it to protect it for when I go caving.
