Blue Lagoon Saltwater UV-C 40W Short – Replacement UV-C Lamp (T5 40W, 365 mm)

Keep your Blue Lagoon Saltwater UV-C 40W Short system performing at its best with this genuine replacement UV-C lamp (article code F980068). This is a T5 single-ended germicidal lamp at 40W, 365 mm in length, with a 4-pin Base C connector — the exact specification for the Blue Lagoon Saltwater UV-C Short 40W. UV-C lamps degrade over time and should be replaced annually (or after approximately 8,000–16,000 hours of operation) to maintain effective disinfection levels.

Why UV-C Lamp Replacement Matters

Even if a UV-C lamp is still lit, its germicidal output decreases steadily with age. Most UV-C lamps retain adequate disinfection power for 8,000–12,000 hours, after which UV output drops below the level needed to reliably destroy bacteria, viruses, and algae. This decline is invisible to the naked eye — the lamp may still glow blue while providing little to no actual disinfection. Regular annual replacement ensures your pool or spa water is always properly sanitised.

T5 UV-C Lamp Technology

T5 lamps are the benchmark in professional UV-C water treatment. The VGE T5 series is engineered to deliver near-constant UV output across its entire 16,000-hour service life, unlike lower-grade lamps that suffer from significant early output drop-off. The compact 16 mm tube diameter enables small, space-efficient system designs. These are single-ended lamps used in professional water disinfection units for swimming pools, spas, and drinking water installations. UV-C radiation at 253.7 nm destroys the DNA of micro-organisms, rendering bacteria, viruses, algae, and even chlorine-resistant pathogens like Cryptosporidium harmless — without adding chemicals to the water.

Compatibility & Installation

This lamp is designed specifically for the Blue Lagoon Saltwater UV-C Short 40W. Always turn off and unplug the UV-C unit before replacing the lamp. Allow the old lamp to cool completely before handling. Wear UV-protective gloves if available and avoid looking directly at the lit lamp. Dispose of spent UV-C lamps according to local regulations — they contain small amounts of mercury.

Tip: When replacing the lamp, also inspect the quartz glass sleeve for cloudiness or micro-cracks. A degraded quartz sleeve reduces UV-C transmission and should be replaced at the same time for maximum effectiveness.
