That's less than 3 wpg
So you will probably want to get 2 sets and that will be plenty for most corals. The one you are looking at is 115 without the bulbs. 2 of those kits will be 230 plus tax and shipping. Then you are looking at another 100 or so for the bulbs depending on where you get them from. That's 330 without the shipping on the light kits. You really need to look at how much a mh diy
kit would cost. We got ours (2 sockets, 2 reflectors, 2 ballasts, and 2 10,000k bulbs) for 350 at the lfs
and the wire at lowes. If you have a basic understanding of electricity, or know someone who does, you should really think about diy mh
. It will be cheaper in the long run.
