Now there is newer technology that will eventually be optimized to the max over time.
There's also less tweaking required with MH. Just put it over your tank and make sure your tank doesn't get too hot. With LEDs, it's a lot easier to burn your corals or not give them enough light. I made this mistake with my Radion. I had it peak at about 80% and things weren't looking too hot. I moved it down to 40% and have slowly ramped up to 60% peak and everything's doing great. I think most people that claim LEDs killed their corals blasted them with too much light.
