55W PL-L UV Bulb (OUTER OF 10)

Description

The 55W PL-L UV Bulb (Outer of 10) is a high-performance replacement ultraviolet lamp designed for use in pond UV clarifiers, including Evolution Aqua EvoUV systems. Operating at 55 watts, it produces strong ultraviolet (UVC) light that effectively eliminates green water by targeting single-celled algae, helping to maintain clear and healthy pond conditions.

Manufactured to a standard PL-L / T8 specification with compatible fittings, this bulb is suitable for a wide range of UV clarifiers that require a 55W lamp. It is commonly used in units such as the Evo 55W UV and Evo 110W systems (which use two bulbs).

Designed for continuous use, the bulb maintains optimal UV output for approximately 9–12 months, after which performance gradually declines even if the lamp still illuminates. Regular replacement is recommended to ensure maximum efficiency and prevent unnecessary energy consumption.

Supplied as an “outer of 10”, this indicates the product is typically packaged as part of a bulk carton of 10 units, making it suitable for retailers or trade purchasing, while still being sold individually.
