I bought this 20w fixture to replace the 3 7w CFL bulbs I had. CFL bulbs were cheap, as were bulbs from other manufacturers, but even at comparable wattages (21W for CFLs and 20W for this device), the fluorescent bulbs produced much more fluorescence over a longer distance, with the added benefit of being omnidirectional and not only in the semi-cylindrical scheme. Other issues I have with this unit are a short (<48") cord, ugly CE stickers on the side of the light that you see when it's installed, and a crappy mylar reflector that pops out right away can be pulled out of the box Real light works and illuminates security ink and other fluorescent items but it's definitely not a high end black light Three stars because it's more or less what you should expect in this price range, definitely not more.
