Each will cover a area of 24 x 24 at 24 inches deep. My problem is my tank is 32 inches deep. Plus they are a little to blue for my eyes. Both units less then a year old. I removed the hanging kit and replaced with bolts to put in my canopy. I still have the hanging kits. Each fixture has 15 violet, blue and white. Each unit is a total of 135W. Has 15 violet, 60 blue and 60 white 1W leds. Non dimable however there is a seperate switch for the blues/violets and whites. Asking $450.00 shipped. Im simply going to get ones that produce more of a 14k color not a 20-22k.
