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.

Reef-safe PAR distribution

ReefLED is Reef-safe as it provides ideal PAR values throughout the aquarium, without hotspots or areas with insufficient light for coral growth. The PAR distribution map shows the actual PAR levels as they vary throughout the cross-section of the aquarium.

ReefLED Programs | PAR vs. PUR

Using PAR measurements only to determine light quality or compatibility of a specific light unit for coral photobiology can be misleading. The PAR measurement was developed to measure the Photosynthetic Active Radiation of plants that is within the visible light region (400 -700 nm).

 

The Photosynthetic Utilized Radiation or PUR that is relevant for optimal zoox photosynthesis is between 360- 480 nm which starts outside the range of visible light (measured by PAR meters) in the UV region and continues into the blue part of the visible light range.

 

PUR cannot be measured directly but must be calculated by isolating the PUR wavelength intensity data for each wavelength from radio-spectrometer analysis.

 

The REEF-SPEC Blue channel of the ReefLED is 100% PUR so for this channel the PUR will actually be slightly higher than the measured PAR due to the UV wavelengths that the PAR meter cannot detect.

 

The 8000K White of the ReefLED has a strong blue peak in the PUR spectrum as well as wavelengths across the whole visible light spectrum and therefore has a PUR of 45% of its PAR.

 

The actual PUR output of the ReefLED will vary according to the combined settings of the Reef-Spec Blue and White channels.

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.
