I'm thinking about installing two florescent, surface-mounted lights in my garage on the ceiling. Instead of cutting up the wallboard that is already installed on the ceiling, I was thinking about using the raceway metal channel designed exactly for that use. Both fixtures would tie in to the existing outlet in the ceiling and the two fixtures have a side hole that the wiring would come out of and into the channel. My question is: how do you tie the wiring into the existing outlet in the ceiling when the wiring will be outside of outlet cover (flush to the ceiling)? Do you drill a hole in the wallboard new to the outlet and bring it into the box that way or something else?
