I installed 4 on my new 180G reef tank. Amazing product. Not sure about the other LEDs on the market since I chose and learned about these in detail. But the ability to control the brightness and K value on a one minute interval 24x7 is amazing. When programmed properly, the brightness and K value change every 60 seconds. And then the clouds are so subtle. I currently have several programs - 5 hour acclimation, 10 hour sunrise to sunset 3500K to 17000K centering on a bright mid day pinnacle of 10000K and then symmetrically backing down thru the brightness and K value towards the sunset. And then a blue or black night that mimics that actual lunar cycle at my GPS coordinates. I am an IT guy, and it took me a month of messing around, but am now at that point where I don't need anyone else's GHL lightcomposer projects. They were helpful at first - when trying to figure out the basics - but there is a point when it all clicks, and you get it. And it is a great place to be.
The other thing I noticed, early days though. I have a brief transitional 3300K sunrise sunset. I blend through this K value from 17000 to darkness or very dim blue moonlight. And during this cycle, everything that hides in the tank during the day come out - starfish, crabs, etc. It is like a party. It may be that this spectrum, while very visible to the human, is not so with invertebrates?
If anyone needs help on the Mitras programming - I am here for you.
