Important: Check Your Existing Lamp Before Ordering

UV lamps can look very similar while having different electrical and physical specifications.

Before ordering, we recommend checking the part number printed on your existing lamp and confirming that it is L-GXO860.

If you are unsure which replacement lamp your system requires, contact our team or send us a clear photograph of:

• The UV system identification label
• The existing UV lamp
• The lamp part number
• The controller or ballast label, where applicable

Our team can help confirm the correct replacement before you place your order.

When Should a UV Lamp Be Replaced?

UV lamps should generally be replaced approximately every 12 months or 9,000 operating hours, depending on the manufacturer’s recommendations and the application.

Importantly, a UV lamp can continue to produce visible light after its effective UV-C output has declined. This means that seeing the lamp illuminated does not necessarily mean the UV system is still delivering the required UV performance.

Regular lamp replacement is therefore an important part of maintaining a UV disinfection system.

Why Replace the UV Lamp Annually?

As a UV lamp operates, its effective UV-C output gradually decreases.

Replacing the lamp at the recommended interval helps:

• Maintain the UV system’s designed UV output
• Support effective UV disinfection
• Reduce the risk associated with an aged lamp
• Maintain reliable operation of the UV system
• Keep routine UV system maintenance up to date

For applications where UV disinfection is being used to protect drinking water or other critical water supplies, lamp replacement should form part of the system’s scheduled maintenance program.

Consider Replacing the Quartz Sleeve and O-Ring

When replacing the L-GXO860 UV lamp, it is also worth inspecting the quartz sleeve and O-ring.

The quartz sleeve separates the UV lamp from the water while allowing UV-C energy to pass through into the water. Deposits, staining or fouling on the quartz sleeve can reduce UV transmission and affect system performance.

For this reason, replacing or servicing the quartz sleeve at the same time as the lamp can be a practical part of annual UV maintenance.

LCS4 & LCE4 Annual Service Kit

For customers carrying out a complete annual service, Water Filtration Solutions also offers an annual service kit for Xylem Wedeco LCS4 and LCE4 UV systems.

The service kit includes:

Frequently Asked Questions

What is an L-GXO860 UV lamp?

The L-GXO860 is a 40W UV-C germicidal lamp used in compatible Xylem Wedeco UV disinfection systems, including LCS4 and LCE4 models.

What Xylem Wedeco systems use the L-GXO860?

The L-GXO860 is used with compatible Xylem Wedeco LCS4 and LCE4 UV systems and is also associated with the UViFLO 4000 range.

How often should an L-GXO860 UV lamp be replaced?

A UV lamp should generally be replaced every 12 months or approximately 9,000 operating hours, subject to the manufacturer’s recommendations and operating conditions.

Does the UV lamp still work if it is glowing?

Not necessarily. A UV lamp can continue to produce visible light even after its effective UV-C output has declined. This is why UV lamps should be replaced according to their recommended operating life rather than simply when they stop illuminating.

Should I replace the quartz sleeve when replacing the lamp?

The quartz sleeve should be inspected whenever the UV lamp is replaced. Fouling, scale or deposits on the sleeve can reduce UV transmission. Replacing the sleeve as part of scheduled maintenance can help maintain effective UV transmission.

What other parts should I replace during an LCS4 or LCE4 service?

Depending on the condition of the system, common service components include the UV lamp, quartz sleeve and O-ring. Water Filtration Solutions offers an annual service kit containing these components.

How do I know if this is the correct UV lamp for my system?

Check the part number printed on your existing lamp. If it is marked L-GXO860, this is the correct lamp type. If you are unsure, send us a photograph of your UV system, lamp and identification labels and our team can assist with identification.
