It's a clear florescent bulb.
Unity, have you tried looking at an aquarium supply store? They sell clear UV Bulbs and fixtures for large aquarium tank disinfecting. You put the bulb into the tank's florescent fixture, turn it on and walk away for a couple of hours. The bigger the tank, the bigger the bulb, the longer the time, but for a 25 gallon tank, its a couple of hours. This kills off the various unwanted microbes that could be infecting your tank. WARNING: Do not look at the blub while it is turned on!I've been hunting for this lamp. In the US it seems $90 is common price. Not a cheap lamp! But I did fine one place online, and I am sure there are more, for less. Two lamps shipped to the US would be less than $120.

Wow, it did come out great! Just curious, do you have any pictures of before the treatment?The monitor was very yellow, almost brown, but this is the result after a few hours (can't believe how nice it came out!)
