Product review (5 stars): Fits QT series too
Though it didn't say so in the product description, this item fits my Broan QT series range hood, and is much cheaper than the one sold on Amazon identified for the QT series (I took the chance because the photo looked identical).  The metal top panel on this one is Galvanized steel, rather than the aluminum of the original equipment one, but I don't think that will matter.  Tips: make sure the metal top panel of the light lens goes above, not below, the protruding fixed sheet metal piece from the range hood, so the lens is not supported only by the flimsy plastic end tabs.  Make sure the end tabs are engaged, otherwise the ends of the lens will be forced closer to the light bulbs, perhaps even in contact, and make sure the bulbs are the right size.  I had a bulb that was 1/4" too long, and it partially melted & scorched the lens.  At the store, I was able to compare the bulb lengths in the package, and could see that some were about 1/4" longer than others
