A150w Ocean Blue. I have it over my Squamosa clam and some sps (Purple Valida) and I don't have it on any controller so I'm assuming its running at 100%??? Please correct me if I'm wrong on this. Is 100% the fallback setting on older Kessils?
Its on for over 12 hours a day usually. Clam seems very happy to be blasted with light and the Purple Valida coloured up extremely quickly (less than a week after being most brown with purple tips from being on the bottom of seller's tank). The 150 is a low powered LED compared to newer Kessil models, and I probably wouldn't use those newer versions in the same way in terms of intensity and duration. Also, my experience has been that it's almost impossible to have too much light for clams and Purple Validas (the more light, the better the colour).
