They look like a new socket ready version of the old Power Compact Lights that I started out with years ago. They used power,produced heat, but grew corals like mad. I am unclear on the strength of PCs, if 10w is enough to do anything.
There is also no reflector. This means that light is going to be shinning out into the room equally as into the tank. It is not like LEDs that will shine straight down. They will need to be in a fixture with a reflector or you will be lighting your room as well.
