Product review (5 stars): Nice, quiet range hood
I replaced an old Nutone from 1979 with this one, using the 7 inch round duct option that vents to the outside.  The fan on low setting was very quiet, but there was still good air flow venting outside on this low setting.  The fan on high setting is noticeably louder, but pushes more air, of course.  For my usage, I'm happy with the low, quiet setting.  I used LED bulbs, PAR20.  When removing the electrical wire knockout, install an approved electrical cable clamp, because it was not included.  Also, get a couple wire nuts to connect your wires.  Follow the instruction manual closely, because you have to manipulate the baffle if you are venting outside.  The instructions were clear, and if you follow them closely, your installation should be fine.
