What To Do With All That Recessed Lighting?

Posted on December 7, 2015 by Scott Gibson in Q&A Spotlight

Justin Brown has moved into a house with lots of recessed lighting fixtures, including 10 six-inch Prescolite non-airtight fixtures on the second floor ceiling, and another 11 mounted in cathedral ceilings.
