I have some comments after building one of these yesterday. First, the parts seemed smaller than typical. Maybe I am just getting old but the resisters were small! Second, as mentioned in various posts, although the parts, manual, and pics are not totally cohesive, I didn't have too much trouble. Manual specs have different color bands than pic or part. Not a real problem as I used a chart and also confirmed with a meter what I was working with. Lastly, for some odd reason, instead of the Vixen logo, I wish an image of Rudolph was screened on the pcb near the power light since it so close and the power light is red.
Anyway, another successful build. Plan to use it for some 10W led spots.
