I'm adding some lights and outlets to a 12 x 20 shed that will be finished with sheetrock to be used as a ceramics studio. I'm putting in six flat panel lights from Costco (LED, 50 W each, choose the K temp) and will have a dimmer switch. Also putting a LED security light on the outside. Just doing the rough in, an electrician will do the panel. Do I have this wired properly? Not to scale, yes I suck at drawing.
