Sphelps is right. About the insane price point. That is an obvious problem for some. But when comparing the two I find no one is throwing in the price of a decent halide fixture.

That plus bulb changes and double my hydro bill also comes to around 3-4 thousand. Over next 5 years. Same time frame of Mh usage before I'd upgrade fixture.

The led is not more powerful or better for growing corals. But it is something that is more efficient and removes the need for a chiller and fans.
