36W PL-L UV Bulb (OUTER 0F 10)

Description

The 36W PL-L UV Bulb (Outer of 10) is a high-performance replacement ultraviolet lamp designed for use in pond UV clarifiers, including compatible Evolution Aqua systems. Operating at 36 watts, it emits powerful UV-C light at approximately 253.7nm, effectively controlling green water by destroying single-celled algae and improving overall water clarity.

Manufactured with a PL-L compact design and 4-pin (2G11) base, this bulb ensures secure installation and reliable operation within compatible UV units. It is commonly used in a wide range of pond clarifiers and sterilisation systems requiring a 36W PL-L configuration.

Designed for continuous use, the bulb provides consistent UV output for effective sterilisation. However, like all UV lamps, its performance gradually declines over time, and it is recommended to replace the bulb every 9–12 months (or approx. 8,000 hours) to maintain maximum efficiency.

Supplied as an “outer of 10”, this indicates the product is typically packaged in bulk cartons of 10 units, making it ideal for trade, resellers, or stocking multiple replacement bulbs while still being sold individually.
