Using Triac Switch to control lights

Hello,

I am looking to switch 3-4 lights on/off at random intervals, and I am hoping to find an "all in one" solution to handle the switching. I know I can get 3-4 relays to handle the power switching, but would something like this work?

And by lights I mean 120v AC powered lights.
