Lifegard 2.5" Clip-On Full Spectrum USB LED Light with In-Line Controller is a cost effective and easy to use LED fixture perfect for pico and nano aquariums. With a full spectrum, most aquarists will use this light over small freshwater aquariums, but it can also be used over small refugiums or macro algae displays in a saltwater environment. The included gooseneck style mount that fits rimless aquariums up to 6mm thick, makes this a budget friendly way of lighting your small aquarium. Plugs into any standard USB power adapter. The built-in in-line controller allows you to easily turn the lights on/off, turn on only the white LEDs, turn on only the red/green/blue LEDs, or even dim the fixture as needed
