Product review (3 stars): Do not buy for a non-ducted install
Just want everyone to know you should read the installation and use instructions on the manufactures website before purchasing a product. That was my mistake. I read lots of reviews to compare the different products I was interested in but not the instructions on the Broan site.

The ventless install seems rather hooky and likely to cause more noise, there should be sones ratings on the non-ducted install. The instructions say if you are doing a non-ducted installation using the two lower fan speeds is recommended.  I bought this model mainly because it was able to be installed non-ducted and because it has three speeds. It seems I wasted my money.  Maybe some day this fan will be able to have a vented install (not in my time here). Until that happens it is not worth the money spent on it.

The stainless is a nice looking addition to the kitchen and yes you can use either Halogen PAR20 50W or Incandescent R16 40W (more expensive), again listed only in the instructions.
