Description

The Hayward Hydrorite UV/Ozone Lamp Replacement, GLX-HYD-LAMPUVO is the replacement UV and ozone lamp for the residential Hayward HydroRite UVO3 sanitizing system. Hayward lists it as Lamp Replacement, UVO Residential, and it is a Brand OEM Hayward part.

Which system it is for

Hayward’s quick reference guide describes the residential HydroRite UVO3 (HYD-UVO) as a 2 inch plumbed system rated for pools up to 60,000 gallons, running on 120 VAC with an operating flow range of 15 to 75 GPM. The system pairs the UV lamp with an ozone venturi. Hayward also shows this lamp as a related part on its commercial HydroRite UV pages, but it is labeled residential, so match it to a residential UVO3 unit rather than a commercial HydroRite.

Why lamps get replaced on a schedule

A UV lamp is a consumable. Its output falls over its service life, and it can keep lighting long after it has stopped doing useful work, so replacement goes by hours in service rather than by whether the lamp still comes on.

Handling

Hayward’s guide shows the ballast cable plugging into the lamp, the lamp sliding into its sleeve, and a clockwise twist to lock it in place. It calls for gloves and no bare hands on the lamp. Route the ballast cable through the large slot, and do not coil the excess or tuck it under the vessel cover.
