I have two of these. I changed the bulb in one last summer but put off changing the other. Aside from taking the screen section off, there are about four small screws that need to be removed to get to the bulb housing. Try not to remove the screws completely because they are very difficult to get lined up back into their holes. If they are removed, you may have to use tweezers or a magnetic screw driver to hold them and get them back in their holes. In addition, make sure the wire is still connected in the bulb housing before you put it back together. Putting the screws back in was the most time consuming phase of the bulb changing process. I almost threw them away becase of it!
