I'm wiring a basement and installing pot lights.
I'd really like to install some pot lights where the cold air return ducts are located.
I was thinking that if I used IC pots with the air sealed housings, that it would prevent the duct from sucking air through the pot light.
I asked the furnace guy if the housing would would restrict enough air to cause any problems and he didn't think that there would be any problem.
Since these ducts are formed by the bottom of the upstairs ceiling, plus two floor joists and the drywall ceiling completing the box, I would think that 12-010(5) would cover this installation and allow the install.
Anybody else agree or disagree?

Thanks... Bruce
