Before You Buy
Key Buying Factors
01
Reef spectrum
Corals need a blue-heavy reef spectrum with actinic wavelengths for growth and fluorescence, so a proper marine spectrum matters. Full-spectrum control lets you tune colour and coral pop.
02
PAR and coral type
Match output to your corals, since soft corals and LPS want moderate PAR while SPS demand high intensity. Choose a system that hits the PAR your corals need across the tank.
03
Coverage
The light must spread evenly across the whole tank footprint, so wider tanks need a longer fixture or multiple units. Even coverage avoids dim corners where coral struggles.
04
Control and ramping
Timers and sunrise-sunset ramping give a natural photoperiod and avoid shocking corals with sudden full intensity. Programmable control is a big benefit for coral health and look.
05
Cooling and reliability
Reef lights run hard, so good heat management and a quality build extend their life over years of daily use. Reliable cooling keeps output steady and the fixture lasting.
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 reef LED system's output to your corals, acclimate new corals slowly to avoid light shock, and choose a light that can deliver the PAR your intended corals require across the tank.
What spectrum is best for a reef tank?
A blue-heavy spectrum with actinic wavelengths suits corals best, driving growth and bringing out fluorescent colours, which is why reef LEDs are blue-dominant. Full-spectrum systems with adjustable channels let you tune the look and meet coral needs, so choose a proper marine spectrum rather than a plain white light.
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 for a natural cycle. Keep it consistent, increase intensity gradually when adding new or light-hungry corals, and use a timer or the system's control to hold a steady, coral-friendly photoperiod.
