I use three of these lights on my Red Sea 900 Reefer 3XL fridge. I have 600 pairs of 6 inch fragrances at 80% lamp intensity. PAR varies by only about 10% throughout the aquarium. Down in the sand in front an average of 220 pairs. At the corners 160-190. The color is very consistent and the flicker is amazing. I also had to get a router with a new version of the software to manage devices that only work on 2.4G (this was also required for other devices). As an old user from the AP700 I find that these turn signals are the best. They're certainly elegant, but it's the color and shimmer that keeps me going with Kessil.
