I am not one to promote other companies and people very often. However, I have found a company with total integrity, who only sell the real and proper black lights for working with fakes and counterfeits. Their prices are fair, they have excellent knowledge and their products are not flimsy cheap pieces, they are good quality. Please feel free to visit their site, and even let them know you found out about them here at my blog. The owner is a genuine and good person to boot: http://www.blacklightworld.com/Contact.htm.
