Can't comment on the LED, but I started my 77 gal with a 36 inch Hagen Glo and it basically started as a FOWLR system. A mushroom coral popped up on its own after a few months under this light (one 10000k bulb & one actinic). I'd say you could probably keep most any soft coral and even a few LPS corals, such as branching Hammer in your size system with that Glo light. They're actually pretty decent lights. Watts per gallon may not be an appropriate measure of your lighting requirements. There's a big difference in the lumen/par output per watt between a Halide, LED or T5HO lamp.
