Product Description

GHO500T5L/4 Hi Output Replacement UV Lamp, 50-55W (G500/HO)

The GHO500T5L/4 (G500/HO) is a high output replacement UV lamp with a 50 to 55W rating, for water filtration systems that use this lamp code. Always confirm the bulb reference on your existing lamp before ordering.

Specifications

Lamp code GHO500T5L/4 (G500/HO), also listed as GPH500T5L/4HA-HO
Type High output replacement UV lamp
Power rating 50-55W

Check before you order

Check the bulb code on your existing UV lamp and go by that reference. High output lamps are not interchangeable with standard output lamps.

Signs you need this part

  • The lamp was last changed 12 months ago or more
  • The lamp no longer lights
  • Your system is showing a lamp warning or fault

Why it matters

UV lamps lose output gradually and well before they stop lighting, so they are normally changed every 12 months rather than when they fail. A lamp past its interval can still glow while delivering less UV than your water needs.

How to fit it

  1. Isolate power to the UV system and let the lamp cool.
  2. Remove the old lamp following your system manual.
  3. Fit the new lamp, handling it by the end cap and avoiding the glass.
  4. Reconnect the lamp and refit any cover.
  5. Restore power and confirm the system runs normally.
