Aquatic Life's 1W Expandable LED Fixture is designed for keeping reef aquariums. The units are available in 24-, 36- and 48-in. lengths and can be linked together as well, so multiple setups can be converted into a single connected setup using included hardware. The unit is sleek-looking, and it is easy on the eyes when either mounted above an aquarium or attached to the sides. But don't let its good looks fool you: This light delivers. Our reviewer said it lit the test aquarium up very nicely, and the 1W LEDs are capable of supporting a reef aquarium. This unit produces plenty of blue light as well. The light also features the ability to change various configurations, including removing each LED lens to produce different lighting effects, such as focusing or spreading out light.
