“Easy to set up (at least on my iphone) in terms of connection and app, the light is 100% customisable which takes time to program. There are certain features that I don't like (progamming the lights makes the lights change to that setting as you do it, stressing fish etc) and there is no cloud setting...it all has to be manually programmed. The light and flexi arm are excellent quality. The range of LEDs is great, blue, deep blue, violet, ultra-violet, green, red and cool white. This will make colours leap out and corals fluoresce. Expect to spend a LOT of time changing settings to find one that suits your tank. Templates are available online from various sources but not from Aqua Illuminations which is strange. All in all a great light!”
