LED's are still priced extremely high (at least those with decent results). It would take you several years to realize the savings in energy cost. We should not forget that LED's need replacement every 5 years. At the current cost and the rate your heater would also be going on and off savings may be a wash. ............ getting the "hidden ray" thing right (appropriate amounts of UV, infra red, and other waves of light not seen by the human eye). ................... If your goal is to make your coral colors look good then yes, blue led's are reef ready now. As far as SPS go, I think they will make corals survive but not thrive. I do believe they will in time but not right now. ............
