Product review (5 stars): User manual and full spec available at Broan website
It's quite on low fan speed, which is sufficient for our cooking needs. I went to the Broan website and downloaded a complete user manual, and a installation guide which were very helpful for installation. I couldn't find them anywhere on Amazon or even a hint they existed. I found LED flood lights at EarthLED that were the right size and shape. They work well with the two brightness feature built in to the Broan. We almost always use the low setting.
