I got one of the cheap UV led lights that Von posted about a while back and so far everything that was supposed to have a UV mark did. I just ran across a President Biloxi $2.50 that doesn't appear to have any UV markings at all. The 2 shown on the Chip Guide both have UV markings. Is there a variety without UV? I've looked at it from several angles... up close and far away... in total darkness and still don't see any UV markings. Could it be a different UV spectrum and just not showing with this particular light?
