Fits like a glove. Finding a 7 inch lantern fairing is not easy. My house was built in the 80's and the standard 6 inch floorboards at the hardware stores are not that size. I used a dimmable LED bulb I found at Costco for $15 and voila. LED light because it is meant to last for many years and can glow in a vaulted ceiling so a very tall ladder is required. I hope to sell the house before I have to change the lightbulb again.
