Anyone looking for a cheap alternative, I am using half a LIFX Z strip on the back of my tank. The I have it sitting on a strip of polystyrene which contours the back of my substrate. Works pretty well and the light spill of my Aquasky RGB creates a gradient with the light. Tank is against a wall which is painted off white.
With LIFX Z you can set a lot of colours, but I have it set on a daily cycle between "ultra warm 2500K" at sunrise/sunset which has an orange tint and something like "noon daylight 5500k" in the middle of the day which gives a slight purple.
This seems to work well on a 60p tank but if you have a large tank or strong main lighting maybe not so much.
