Swell 55 Watt PLL UV Bulb
This Swell 55 Watt PLL UV Bulb has been made just for Swell UK customers, and replaces other 4-pin, single connection UV bulbs in your garden pond UVC for a fraction of the price of a branded model.
Product Information
Swell 55w PLL UV replacement Bulbs / Tubes are ideal for UV clarifiers, filter sets and any pond equipment that uses a 55w PLL twin tube, four pin lamp.
Utra Violet light binds together algae cells for easy filtration and removal. Left unchecked algae can cause thick, murky water that starves fish and plants of oxygen, light and nutrients. Our own brand UV lamps ensure that your pond looks great all summer long.
Like all of our own brand products, these UV lamps are made to the highest standard and offer a long service life. They also offer great value for money, as when you buy one, you get one free!
Key Features:
- Swell PLL Bulbs are a single ended, twin tube with four pins at one end.
- High UV output allows for greater algae control.
- Can be used on: Oase Bitron, Blagdon UV's, Aqua Medic UV's and any other UV device that requires PLL.
- Buy one get one free!

The Swell 55 Watt PLL UV Bulb does not fit the Bitron C 110watt UV unit as stated in the write up. Bulb holder spacer cannot fit over the two bulbs because of width of bulbs. Hence the bulbs touch each other in the unit. -
