DII LED aquarium lights

DII LED makes LED lighting for reef and freshwater tanks. Our range of DII LED aquarium lights includes fixtures and the parts to mount and power them.

Choosing a DII LED light

Match the fixture to your tank's length and the corals you keep. For example, brighter fixtures suit SPS corals, while moderate output works for soft corals and LPS. Also, check that the mounting parts fit your tank's rim before you order. Browse all our reef lighting to compare brands.

Common questions

How high should I mount my LED light?

Follow the maker's guide for your fixture. In general, higher mounting spreads light wider but makes it less intense. So a light mounted higher can cover a longer tank, while one mounted lower gives more punch to the corals right under it.
