ReefLED Lighting

Years of research and testing are behind Red Sea’s ReefLED smart reef lighting system. These lights have been designed to ensure optimal coral growth and dramatic coloration, while creating a gentle shimmer throughout the aquarium.

The ReefLED lights are guaranteed to be reef-safe and REEF-SPEC and are very easy to set up.

The built-in wi-fi connects them directly to the internet, enabling you to control them from your smartphone using Red Sea’s ReefBeat smart aquarium app.

At the heart of the unit is a single, compact LED array that includes a multi-wavelength, 23,000 Kelvin “REEF-SPEC Blue” channel (a proprietary blend of blue, violet and ultraviolet LEDs) which, together with an 8,000K White channel, provides a reef-safe range of color temperatures that enable all corals to flourish.

In addition, a separate dedicated 3W moonlight channel provides low levels of light for reef-safe night-time viewing.

ReefLED also includes an optical-glass, hollow lens that ensures a homogenous light spectrum with ideal PAR values throughout the aquarium, without hotspots or areas with insufficient light for coral growth.

ReefLED is controlled by Red Sea’s ReefBeat app which provides a number of preset lighting programs you can choose from as well as additional features including sunrise/sunset effects, lunar cycle moon light, random clouds and even an acclimation program for new installations. ReefBeat also provides best-practice guidelines during setup as well as useful notifications to your smartphone, for example, in the event of a power outage.

  • REEF-SPEC light output for optimal coral growth and coloration
  • Homogenous light with a gentle shimmer
  • Reef-safe dual-channel color setting plus dedicated moonlights
  • ReefBeat app for easy set-up, operation, monitoring and notifications
  • Anti-glare recessed lens

The ReefRun DC return pump is run via the ReefRun Dual Controller as it can also operate the Reefer DC Skimmer at the same time!

Reefer DC Skimmer

Efficient. Quiet. Smart.

The REEFER DC Skimmers include self-leveling technology that prevents over-skimming and full cups from spilling while continuing to aerate the water.


The Self-leveling feature is activated whenever the wetness of the foam in the neck exceeds the user-adjusted “over-skim” threshold. The intensity of the pump is immediately reduced to prevent the over-skim and then gradually increased or decreased, a bit at a time, according to the foam wetness, until the preset pump intensity is reached and stable skimming is restored.

Optimal Waste Removal

The Reefer DC Skimmer features a combination of self-leveling tech, a PSK DC pump, proportionally sized venturi, a bubble diffusor and reaction body that optimizes air-water contact time.

Sensor to pump

The REEFER DC Skimmers come with a dual-action solid-state sensor that monitors foam wetness and waste level, allowing the ReefRun Dual Controller to regulate the DC Pump accordingly.


The REEFER DC Skimmers are exceptionally quiet due to the PSK DC Pump, rubber connectors and an air intake silencer.

The Reefer DC Skimmer is run via the ReefRun Dual Controller as it can also operate the ReefRun DC return pump at the same time!

Combine them into your ReefBeat eco system for more efficient reef keeping.

And use the ReefBeat
Create your unique Feed scenario by switching selected pumps off or run at different intensities at different times for different durations.

Select the order and timing between switching devices back on after a maintenance shutdown, such as allowing a few minutes for your return pump to restore water levels in sump and aquarium before switching on the skimmer, wave pumps and dosers.
