My lights are 120° lens and produce what I would say is a 12000 k to 14000 k light. The colors can be manipulated but I think Noopsyche has done a great job with these lights. The controls are somewhat limited but it is a very straight forward light that is getting good results with my Monti and zoas. If you want to know the exact lights I am using check out the Noopsyche K7 Pro II lights. This system I built also has auto water change and top up. Now when I say auto water change it is NOT using a auto water changer but I do have the ability to draw water from my tank quickly, hit a switch and it fills with new saltwater. After this tank fully settled I am hoping not to have to do water changes at all or very little. As you can see, early morning here, inhabitants still waking up.
