You can make out the rainbows up close and at this angle..It was really
tough to get them to show up as they are very faint, but present on the
whole light. my guess is the machining process was hot enough to slightly
heat anodize it. It looks absolutely amazing! I have not put the light down
since receiving it.
sorry for the blurry pic, but had to get closer than macro mode could
focus to see the anodizing effect.
