Fish tank lighting control units are ballast sets that allow you to install fluorescent tubes in your fish tank without the use of a full canopy. The control units typically have a waterproof (IP67) plastic housing (refer to each product for full spec). They include mounting clips for flexibility of installation and electronic ballast.
We have a selection of units from leading manufacturers Aqua Medic and Arcadia, so you can be sure of a quality product at a discounted price. Aqua Medic's T5 Starter Unit is available for one or two bulbs. It does not come with lamps fitted, but they are available here at Swell UK.
