Blue Lagoon UV-C lamp 42 watt
Do you notice that your pool water is no longer as clear and fresh as you're used to, even though your UV-C device is running normally? There's a good chance the lamp needs replacing. A UV-C lamp gradually loses its power, long before it fails completely. This Blue Lagoon UV-C lamp of 42 watts restores the full disinfecting effect, so your water becomes crystal clear again.
This lamp is the original replacement for the Blue Lagoon Xpose UV-C 42 watt. A quick and cost-effective fix that lets your existing unit perform like new again, without having to replace the entire device.
Why you should replace the lamp on time
UV-C light kills bacteria, algae and other micro-organisms in your water. The problem is that you can't see with the naked eye that the lamp is getting weaker: it keeps burning, but delivers less and less UV-C. The result is cloudy water, more algae growth and higher chlorine consumption. By replacing the lamp on time, you keep disinfection at the right level and ultimately save on chemicals.
A good time to replace
This lamp lasts around 9,000 operating hours. For most pools, that amounts to roughly one swimming season of continuous use. We recommend replacing the lamp at the start of a new season, so you start the year with optimal performance and won't need to worry about it for the whole summer.
