And as for the TRIM… Well I will let you google that but I promise you I’m correct:)
How about this…go to
http://www.acuitybrandslighting.com/Library/PSG/ResidentialRecessed.pdf
and download their info…read it carefully any notice it’s specific trims that make a traditional recess can acceptable in damp or wet locations…remember the can itself is above the 8’ mark…it’s in the ceiling. All manufacturers offer these trim options for there standard cans. Always keeping mind that some of my manufacturers make wet and damp location recess luminaries without trims…it’s all about the listings.
