Please check the base before ordering. These are the GX23 version with two raised locating fins/lugs on the plastic base. They are different from the G23 version, which has a single raised locating fin/lug. Both styles use two electrical pins, so compare the plastic keying shape with your existing lamp and the product photos.
Some older Hozelock Bioforce 12000 filters also use the 13W two-lug/double-fin lamp, but that model was supplied with more than one 13W base style. Please check the existing bulb or socket before ordering.
Also suitable for other 13W UVC pond filters and clarifiers that specify the same GX23 double-fin/two-lug fitting. We recommend replacing UVC lamps approximately every 12 months to maintain strong UV output.
