I took the innards out of an old 12V fluro light, the kind that you can use in an automotive environment. I bought a UV tube and replaced the original tube with it. I placed some black static foam inside a small wooden drawer and place the chip on this. The tube is rested directly on the chip and is then powered by a 'Plug Pak' powersupply. This seems crude but it only cost me the price of the tube ($15) and has worked well for over 5 years. Tony Just when I thought I knew it all, I learned that I didn't.
