Exactly. He was only going to use it as a refugium light. They actually work surprisingly well for this. Very little heat, waterproof, more than bright enough for cheato, small size (fits in a compact space), has a mounting bracket, and the LED
color can be changed out very easily for 3-5 bucks shipped.
I've tried the 6000k, 10000k, 20000k and royal blue emitters just for fun. I also have a super blue chip but I haven't tried it out yet. I wouldn't recommend going all in with them on a display tank but I do plan to check if they can be used in the sump to house frags at some point. I can't say they'll work for corals but for cheato they're doing fine and they grow more coralline on the rock in the sump than the single 22" T5 that was over the sump before switching to these floodlights. For this one application I find they're definitely worth considering.
