Two 55w PLL UV bulbs in one delivery. A UV lamp is an annual consumable, not a one-off purchase. Buying two at once means one delivery charge instead of two, and a spare already on the shelf when the water turns.

Fits our own brand

AllPondSolutions CUV-155 and SSUV-55 sterilisers, and the SSUV-110 which takes two lamps; PFC-25000, PFC-30000 and PFC-50000 filters; AUTO-PFC-30000, AUTO-PFC-50000 and AUTO-PFC-75000; PRO-30000, PRO-50000 and PRO-75000. Also fits all major manufacturers' units - measure your existing bulb end to end and check it against 535mm before ordering.

Running an SSUV-110? That unit takes two lamps, so this pack is exactly one full set.

When to replace it

A UV bulb stops working long before it stops glowing. The visible light remains while the invisible UV-C output fades, so a lamp that still lights up can be doing nothing for your water.

• Sterilisation: replace every 6 months (approximately 4,000 hours)
• Pond or aquarium clarification: replace every 12 months (approximately 8,000 hours)

Clean the quartz sleeve at every change - see our UV Steriliser Maintenance Guide.
