The Arcadia Eco-Aqua LED adapters clip on to each end of an Arcadia Eco-Aqua lamp, allowing it to fit into existing T8 aquarium light fittings. With the clips fitted, the Arcadia Eco-Aqua lamps are the same length as equivalent T8 fluorescent lamps. For example a 9W Arcadia Eco-Aqua lamp, which is equivalent to a 15W T8 aquarium lamp, is the same length as a 15W T8 lamp when the clips are fitted. Adapter clips are compatible with the majority of aquariums supplied with a central T8 light unit with waterproof lamp holders (e.g. Juwel Multilux T8 light units).Do you have questions about this article ?
