Product Information

Red Sea's ReefLED 50 is smart, safe and efficient. Years of research and testing are behind this smart reef lighting system, which is suitable for aquariums of up to 50cm depth. ReefLED 50 provides optimal coral growth, dramatic coloration and a gentle shimmer throughout your aquarium with effective coverage of 50cm x 50cm.

ReefLED lights are guaranteed to be reef-safe and REEF-SPEC and are very easy to set up. They also come with 12 months guarantee.

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 colour 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 homogeneous light spectrum with ideal PAR values throughout the aquarium, without hotspots or areas with insufficient light for coral growth.

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. The ReefBeat app 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.

The ReefLED 50 universal mounting arm is suitable for tank widths of 36-51cm (14-20") with a glass thickness of 8-15mm (5/16"-3/8") and can be rotated from side to side during reef-scaping or other tank maintenance.

    Red Sea ReefLED 50 Universal Mounting Arm
    Feefo Logo
    Nicely made arm (for LED 50).
    Only problem I had was that my tank was set against the wall, and there is insufficient room for the fittings between the tank and the wall.
    Rather than return the arm, I ended up stripping the tank down, and moved it from the wall. Bit of a bother, so bear this in mind.
