Yeah, I agree. Bad idea. Not only is UV dangerous, you can't really put a UV bulb directly in water. They're typically used with a quartz sleeve. These quartz sleeves need a watertight seal at the connector end. Trying to DIY something like this just isn't worth the trouble. By the time you get a suitable housing, transformer, bulb, quartz sleeve, and connections you'll have spent more than just paying for a real one.
