Arcadia Ultraseal Light Controllers are a safe and secure way of fitting and controlling your T8 fluorescent lamps.

Suitable for a variety of sizes, these electronic controllers are waterproof to IP67 standard. They include universal mounting brackets which allows for easy attachment to the hood or wall of the fish tank. Available in both single and double control units, please see the information below for the correct size for your tank. Please note that the double controllers are magnetic, not electronic.

If you have a T5 lamp, the ACU08 is a perfect controller. The tube must be 12mm in diameter. The rest of the range is only to be used with T8 lamps.

The controllers can be used with the Arcadia Lamp Reflectors range too.
