            The REEFER-S Deluxe incorporates the ReefLED 160S lighting units with Red Sea’s custom mounting system into these reef-ready systems in a convenient single package.
            At the heart of the ReefLED is a compact Led array that provides a reef-safe range of REEF-SPEC light through a single REEF-SPEC Blue (23,000 Kelvin) channel that consists of an optimum combination of ultraviolet, violet and blue LEDs and an 9,000 Kelvin white channel.
            In addition, it has a separate dedicated 3W Moonlight channel to provide the low levels of light for reef-safe nighttime viewing.
            The ReefLED 160S combines 160W of REEF-SPEC & Reef-Safe LED light with a patent-pending stadium-shaped lens, creating a beautiful, homogeneous spread throughout an aquarium of 80cm / 32’’ in all three directions.

            ReefLED is controlled by Red Sea’s ReefBeat App, which provides a wide range of easy to use functions such as random clouds, acclimation for new installations, and a lunar cycle for the moonlights.
            The custom mounting system attaches firmly onto the rear wall of the tank and can be rotated to the upright position during reef scaping or other tank maintenance. The REEFER™ Peninsula Deluxe comes with a customized hanging system for the ReefLED lights.

                Nicholas Jefferies Gröhn REEFER 425 G2

                What can I say, the Red Sea G2 is the new benchmark in Reef aquariums. I have had a number of Reef tanks over the 16years of Reef keeping and hands down this would have be best one ☝️ I have set up to date. I love the new coloured plumbing, the new gate valve is so easy to uses, plus having the sump reef mat Ready is a winner for me
