The replacement 3 W CCFL bulb for the Fluval UVC In-Line Clarifier Unit. Fluval rates it at 30,000 hours, which it describes as more than three years of continuous use. The honest caveat is that UV output falls away long before the lamp stops lighting up, so a bulb that still glows is not necessarily still clearing the water — replace it on hours run, not on appearance.
Fits the Fluval UVC In-Line Clarifier Unit 3W, Fluval item A198; Fluval lists the bulb itself as #A19998. It is not the 6 W bulb used by the FX Series clarifier.
