5 Watt Compact Ultra Violet PL Bulb

4.5" (100mm) Long

G23 Base 

Regular replacement of the UV bulbs in your pond UV Clarifier is one of the easiest, but most effective ways to ensure you have a crystal clear pond, free from green water all year round.

The arcadia replacement UV bulbs will fit most models of UV units, including aquarium sterilisers.

We recommend that you replace the bulb in early spring, once the last frosts have gone, so that they can be working before the long warm sunny days of summer arrive!

The compact PL bulbs give a strong output for upto 1 year

WARNING - Never look directly at an illuminated UV bulb.
