These bulbs are supposed to last several months. I purchased in July and it went out two weeks ago

All Bug zappers attracts and kill, but what is so important is it self cleans or comes close. I was not paying attention. Then notice after three days bug more then normal at night with zapper on. I noticed this in the morning. Not good for me, a lot of the time I can’t come out everyday to clean. Well needless to say this is going back, a faulty design. Onto the next attempt, which will be an led one I saw..

No instructions for how to replace this bulb and it was not fun. You should be able to reach through the openings to remove the protective shield and remove the bulb, but that is just not possible. I tried multiple times. Instead, I had to remove the top shell (8 tiny sheet metal screws) and then top plate (3 more tiny screws). Then I had to remove the bulb shield (1 screw) and then the bulb retainer screws (2 more screws). And then, unable to reach the bulb housing, I tugged on the bulb, only to have it fall apart in my hand (see photo). TERRIBLE design. It took me 8 minutes to disassemble with a power screw driver and 15 to put it back together. The top lid is very difficult to align. NOTE: Mark the top cover with some white paint or white out, so you know how to realign it. Terrible design. And one the second unit, I tried to lower the bulb assembly from the top (4 more screws), only to have the connecting wires come off !? I have several of each of the smaller units and they aren't much fun to change out the bulb, but this one was by far the most difficult. At least use thumb screws and find a way to change the bulb without removing the top assemply. That's just wrong and who wants to do that every 41 days ?
