Our client in Germany recently added PR72 Super Blue LED Pendants to his huge 6,000 gallon reef tank. The video shows the PR72 Super Blue in operation only. His main lighting is provided by the Atlantik AT P300 LED Pendants. At a depth of nearly 7 feet, the PR72’s Super Blue spectrum easily penetrates the water and highlights the red and blue pigment of the coral during the full lighting cycle and also serves as a great moonlight as shown in the video.
