I actually DO NOT want to light the entire tank right now, however, I do want to avoid some of the spotlighting that can occur. I do like the darker/deeper look to the water as seen with some of the spotlighting effect though; I think it is far better than the typical light-box seen so often. I can hang bulbs anywhere from a few inches to a few feet above the tank since it's an in wall system. This will start as a FOWLR system and could grow into something more in the future. I DO NOT want to go with one of the kits, but prefer the PAR38 bulbs. Ideally, how high above the tank should I hang this light to avoid such spotlighting? Should I worry about 60 or 80 degree lenses? With the 7 LED bulb, what would the Kelvin rating be most comparable to? Just for giggles, how many of these bulbs should be over a FOWLR and reef system? Thanks for the time.
