In my distant memory of aquarium keeping and such, where UV lights are 
sometimes used to kill bacteria in a water jacket around them, they do 
lose their effectiveness... as I recall a year (although, always on for 
that year) would be enough to see a serious reduction in effectiveness.

Not a particularly useful reply, but I guess it's also on of those 
****fans things, too...
