Red Sea’s ReefLED series is the result of years of research into the lighting needs of corals in artificial environments. Uniquely designed with a light intensity and spectrum that is 100% utilised by the corals, ReefLED lights are 100% reef-safe & 100% REEF-SPEC, providing optimal growth, vivid colours, and an elegant gentle shimmer throughout the aquarium. The ReefLED 90 provides REEF-SPEC PAR levels of 500 beneath the lens at water surface, to 150 at 50cm / 20’’ depth. It is therefore the smart choice for medium-size tanks. At the heart of the unit is a single, compact LED array, providing 90W of REEF-SPEC & Reef-Safe LED light. It includes 80W of multi-wavelength 23,000 Kelvin REEF-SPEC Blue (a proprietary blend of blue, violet and ultraviolet LEDs), together with 10W of 9,000 Kelvin White, and a separate 3W channel for moonlight. This array enables a wide range of REEF–SPEC light that will please both you and your corals. The ReefLED 90 is also equipped with a built-in Wi-Fi that allows total control via ReefBeat smart aquarium app (which controls all Red Sea devices). The app includes pre-set lighting programs, along with additional features such as sunrise/sunset effects, lunar cycle moon light, random clouds and even an acclimation program for new installations. Features REEF-SPEC light output for optimal coral growth and colouration 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 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 Zooxanthellae 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 9000K 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 RedSea LED will vary according to the combined settings of the Reef-Spec Blue and White channels.
