here man try this out http://www.superbrightleds.com/moreinfo/1605/
Now i have to say I do not own any UV lights but like you I'm thinking of buying or building one but the price of these it would be hard to do . I'm also looking into building my own green fishing light as well I can't get over what they want for simple led fishing lights or the fact that people are paying that kind of money for them ..
