The Submersible UV 40W Lamp is a high-output UV-C sterilisation solution designed for fully submerged installation inside koi pond filters and drum filtration systems. Because it uses advanced amalgam lamp technology, it delivers powerful germicidal performance while maintaining stable UV output over a long service life. As a result, pond owners benefit from improved water clarity, reduced algae growth, and a healthier environment for koi.
How the Submersible UV 40W Lamp Improves Water Clarity
This professional UV-C lamp operates at the optimal 254 nm wavelength, which effectively neutralises green water algae, harmful bacteria, viruses, and pathogens. Consequently, it helps maintain crystal-clear pond water while reducing organic loading on biological filtration systems. In addition, early sterilisation prevents waste from breaking down into ammonia, therefore supporting more stable water quality.
Why Choose a Submersible UV 40W Lamp with Amalgam Technology
Unlike standard UV bulbs, amalgam technology provides consistent germicidal output across varying water temperatures. Therefore, the Submersible UV 40W Lamp maintains reliable sterilisation performance throughout the year. Furthermore, the advanced design improves efficiency while reducing energy waste.
Key advantages include:
• Stable UV output in changing temperatures
• Higher sterilisation efficiency
• Extended operational lifespan
• Reduced maintenance requirements
Installing the Submersible UV 40W Lamp in Drum Filters
The fully submersible design allows direct installation inside drum filters and filtration chambers without restricting water flow. Because it operates internally, it does not create pressure loss or reduce filtration efficiency. As a result, it integrates seamlessly into professional koi pond filtration systems.
Therefore, it is ideal for:
• Red Label Drum Filters
• Combi drum filtration systems
• Moving bed filter chambers
• Professional koi pond installations
Long Lifespan for Reliable Performance
The Submersible UV 40W Lamp offers an extended service life of approximately 13,000 to 16,000 operating hours. Consequently, pond keepers benefit from fewer replacements, lower running costs, and consistent sterilisation performance. In addition, the stable output ensures reliable water clarity over extended operating periods.
