Coral is photosynthetic, so light is what drives growth and colour in a reef tank. A good reef light delivers the right spectrum, enough PAR for your corals, and even coverage across the tank. We compared reef LEDs on spectrum, output, coverage and control, from clip-on nano lights to fuller-spectrum fixtures, so you can match the light to your corals.

Before You Buy
Key Buying Factors
01
Spectrum
Corals need a blue-heavy reef spectrum with actinic wavelengths for growth and fluorescence. Full-spectrum control lets you tune colour and pop from your corals.
02
PAR and coral type
Match output to your corals. Soft corals and LPS want moderate PAR, while SPS demand high intensity, so choose a light that hits the levels your corals need.
03
Coverage
The light must spread evenly across the tank footprint. Wider tanks need a longer fixture or multiple units to avoid dim, shaded corners where coral struggles.
04
Control and ramping
Timers and sunrise-sunset ramping give corals a natural photoperiod and let you avoid shocking them with sudden full-intensity light.
05
Cooling and build
Reef lights run hard, so good heat management extends their life. A well-built fixture with quiet cooling lasts longer over years of daily use.
06
Mounting
Clip-on, arm and hanging options suit different tanks. Check the mount fits your rim or rimless tank and lets you set the correct height for your corals.
Frequently asked questions
How much light do corals need?
It depends on the coral. Soft corals and many LPS thrive under moderate PAR, while SPS corals need high intensity. Match the light output to your corals and acclimate them slowly to avoid light shock.
What spectrum is best for a reef tank?
A blue-heavy spectrum with actinic wavelengths suits corals best, driving growth and bringing out fluorescence. Full-spectrum lights with adjustable channels let you tune the look and meet coral needs.
How long should reef lights be on?
A photoperiod of around eight to ten hours suits most reef tanks, ideally with sunrise and sunset ramping. Keep it consistent, and increase intensity gradually when adding new or light-hungry corals.
