Do they work yes? They are 400w halides, even the lowest PAR, most inefficient 400w MH will grow your corals. However, my experience with the 15k was that growth was slower than with a 20k XM bulb. And the 15k was yellow, very ugly, it was like I had a whole new tank when I switched to XM.

any others with advice on this? Are they going to burn my house down? Or just not last as long?

They are OK. Just poor color and very little coral growth, from them.
