I suppose I should elaborate a bit on my last post. My recollection is you can turn the fan counter clockwise to detach it from the bulb. Assuming you already have the dust cover off the light and the old bulb removed, you put the new LED bulb in and put the retaining clip back in place. Then you put the rubber dust boot back on. After that, you re-attach the fan to the bulb through the wiring hole in the dust cover. that last part is what I was referring to. The connection between the LED bulb and the fan is very snug to begin with and when you add in having to compress the dust cover to marry the bulb back up with the fan, it can be a bit of a pain in the butt, but, it does go back together without any modifications.
