The Classica Stretch LED lamp combines innovation with a functional design. This is a very low profile LED unit that extends to fit over various lengths of aquarium making it in our opinion of the most flexible units on the market to suit most aquarium sizes from Nano aquariums right up to 1.5 Metre Aquariums! The units are slim, lightweight and versatile. They are IP67 rated so are fully waterproof and come equiped with a dual switch controller (with a 1.8m lead) enabling you to move between daytime and night time modes along with optional mounting clips for additional security when fitting theunit to your aquarium. The WA Team believe this is a great unit for the cost especially as the Stretch is so slimline you can add as many units side by side in your tank to get a truely dazzling effect! Comes complete with a 2 year warranty. The Stretch is also available in a freshwater version. Please see the Specifications image for detailed information!
