This Pro Lights UV-C bulb is a direct replacement for the Tetra Pond 19526 – the one used in the Tetra UVC5 pond clarifier.
It's a 5-watt bulb with a G23 (two-pin) base, 34 volts, and a wavelength of 254nm – the sweet spot for killing algae and bacteria in pond water.
Average life is a solid 10,000 hours, so you won't be changing it every season.


Just a heads-up: the Tetra name is trademarked and this is a compatible replacement, not an OEM Tetra bulb.
