This is second try at this. I'm loosing a lot of time trying to space the lights correctly but I'm still within the hour allotted.
Is it better to have the light spreads overlap a little or not quite overlap?
I went with a strategy of putting diffusers on one side of room and returns on the other. Now I see a large area in the middle that doesn't have diffusers. Does this matter?
How close can the diffuser get to the wall? Return grill?
Any comments welcomed. Thanks for looking.
