recessed lighting basic question
In midst of DIY kitchen reno and slowly going thru recessed lighting posts.
How do people pick 4" versus 5" versus 6" cans? I'd come to the conclusion that 4" meant small cans taking small 50W PAR20 and 5" meant 75W PAR30, i.e. similar beam angles (similar spacing) and different foot candles. Some posts mention they have mixed 4" and 5" in their kitchen. What are they using for what? and what's the decision process? Large cans for high ceilings or what?
I've found that self-taught means you can know some complicated stuff and be completely ignorant of some basic stuff. I keep thinking I'm missing something here :)
