> I'm sure having a UV filter of your water would not go amiss

You don't need lased light for that (and using a low efficiency, high cost device also not ideal?!).

UV LEDs seem to be in development. The problem with UV fluorescent tubes is that they have horrible cycle life.

I guess everyone means UVC here. A UVA flashlight is cheaper than lunch ;) edit: my facts were scrambled. C is the nasty one... maybe my favorite (unsafe) language will help me remember that from now on.
