Is this light only for saltwater refugiums?

Yes. Its spectrum is tuned for growing macroalgae in a saltwater sump. It is not intended as a display light for corals or freshwater plants.

How much refugium does it cover?

About 20 inches of width. For a wider refugium, two units or a larger fixture work better.

Can I dim it and set a schedule?

Yes. Intensity is adjustable and schedule mode runs a set photoperiod, which suits a reverse lighting cycle.

Does it need a controller or app?

It has built-in smart control, so no separate controller is needed. Expect to spend some time on the initial setup.

The light fixture, a power adapter and a 20 ft cord. Check whether a mounting bracket is included for your sump.

Will it bleach my macroalgae?

At full power in a shallow refugium it can. Start dimmed and raise intensity gradually.

Our take on the Prime 16 LED Fuge Light

The Prime 16 Fuge is a small puck-shaped LED fixture built for saltwater refugiums. It mixes UV, violet, cool white and phyto-red LEDs at 46 W to grow chaetomorpha and other macroalgae that pull nutrients out of the water. A smart controller adds dimming and a schedule mode, so you can run a reverse photoperiod without a separate timer. It is more capable than a plain grow bulb and simpler than a full reef fixture, and owners rate it well for macroalgae growth.
