The Red Sea ReefLED G2 115 is a premium, compact smart LED reef fixture engineered to provide high-intensity light output, maximum coral health safety, and exceptional fluorescence. Built around a single, highly concentrated ovoid-shaped LED array, the unit aggregates all its diodes into a central puck. This layout is covered by a patented, single optical-glass lens that perfectly blends the individual colors before they exit the fixture. The wide-angle optical spread maximizes light coverage while delivering a natural, cohesive underwater shimmer without localized hotspots or color separation.
A major feature of the 2nd generation (G2) architecture is its Dynamic Power Management chipset. Unlike fixtures that limit power per channel, the G2 115 can route its full 115 Watts of electrical current across the adjustable color scale, maintaining maximum intensity whether tuned to a crisp 10,000K reef daylight or a deep 23,000K actinic blue. The fixture is housed in a sleek, matte black enclosure featuring rounded corners and a slightly recessed lens array that acts as an integrated glare shield. It is managed by smart thermal sensors that regulate a quiet, top-mounted active cooling fan. Wireless programming connects directly over local Wi-Fi/Bluetooth via the ReefBeat mobile app.

LED Spectral Channel Breakdown
The G2 115 array targets the precise Photosynthetically Usable Radiation (PUR) spectrum needed by zooxanthellae algae, intentionally omitting wavebands above 480nm (greens, yellows, and reds) that can fuel toxic oxygen radicals and unwanted algae:

ReefBeat Safe-Exposure Software: Built with an integrated exposure calculator that automatically cross-checks your photoperiod, color spectrum, and total intensity against Red Sea’s biological research database. The app displays your settings as a direct percentage of the maximum recommended daily light dose, preventing accidental overexposure and protecting sensitive corals.
-
Smart App Programming Suite: Includes advanced control features like a 28-day automated lunar cycle simulator, randomized cloud cover generators with three selectable shading intensity levels, and an automated acclimation mode that gradually steps up PAR values to smoothly transition newly introduced livestock.
-
Photography Mode & Custom Presets: The ReefBeat interface features quick-access macro keys on the dashboard, including a specialized, high-actinic coral photography preset. This allows you to temporarily switch the tank to an ultra-fluorescent spectrum for quick mobile shots before automatically reverting to the primary daily lighting schedule.
-
Ecosystem Hardware Compatibility: Designed to be backwards compatible with original generation mounting accessories. The rear tracks secure seamlessly onto the single-light Red Sea Universal Mounting Arm (90/115 size), the multi-light horizontal tracking pendants, or overhead ceiling wire suspension kits.
