Red Sea ReefLED G2 60 / 115 / 170W — Reef-Safe Reef-Spec LED for Corals

The Red Sea ReefLED G2 is the next generation of 100% Reef-Safe LED lighting for reef aquariums. Based on 35 years of research on the needs of corals in artificial environments, the ReefLED G2 features a new LED chipset with an enriched REEF-SPEC spectrum including more violet, ultra-violet, and boosted 470nm blue for unprecedented coral fluorescence and coloration. Available in three power levels (60W, 115W, and 170W), the range covers aquariums of all sizes from nano reefs to large REEFER systems. Color temperature adjustable from 8,000K (reef white) to 23,000K (REEF-SPEC Blue), at full power from 10,000K and up.

REEF-SPEC Spectrum — 100% Reef-Safe

The REEF-SPEC spectrum is engineered to deliver only the wavelengths useful for zooxanthellae photosynthesis (380-480 nm), without the harmful wavelengths (greens, yellows, reds) that generate excess heat and toxic oxygen radicals damaging to corals. The ReefBeat app automatically checks your settings and warns you if the recommended daily light exposure is exceeded.

Frequently Asked Questions

Which ReefLED G2 should I choose for a Red Sea REEFER 350?

The REEFER 350 typically uses 2 x ReefLED G2 170 or 3 x ReefLED G2 115 depending on depth and coral type. For a mixed reef, 2 x G2 170 provide full coverage. For an SPS-dominant system, 3 x G2 115 at 50 cm spacing deliver more uniform PAR.

What is the REEF-SPEC spectrum and why does it matter?

The REEF-SPEC spectrum is exclusive to Red Sea. It delivers only the 380-480 nm wavelengths useful for zooxanthellae photosynthesis, without the harmful wavelengths that can damage corals. The ReefBeat app automatically monitors your settings to ensure exposure stays within safe limits.

Is the ReefLED G2 compatible with older ReefLED 50/90/160S mounts?

The G2 Hanging Kit is compatible with the older 50, 90, and 160S models. For mounting arms, check model-specific compatibility: the 90/115 arm and the 160S/170 arm are separate products.
