recessed can size differences
Before last week I never had thought of recessed lights beyond being one type: "recessed" ... suddenly there are 3", 4", 5", 6" sizes... IC, non-IC, air-tight, non air tight, white trim, black trim, eye ball... then there are LED, CFL and regular bulbs! Whew!
I currently have an "L" shaped hallway on my first floor, each leg is about 10' and currently we have just one light down at the end... so it ends up being very dark at the other.
My electrician friend, doing other work in the house, has suggesting converting the existing light to a "can", adding one of the 90* part of the L, and another down at the other end, a total of 3 lights.
These would be retro-fit installations. I'm planning to get air-tight and IC because I have a Cape house, so I want to minimize potential air flow into the knee wall, and there is some light insulation between the first and second floors as the second floor was originally just an unfinished attic.
So my long winded post boils down to--Can someone help me understand the pros and cons of the various sizes of the cans? Is there any one brand that is easier or better for retrofitting? I'm planning to mount and install them myself if that affects your advice.
