### ⭐⭐⭐⭐⭐ Exactly what you need
*by J***E on August 25, 2025*

As long as this is the right bulb for the bug zapper you have, it works great! Don't buy the aftermarket ones that are only half the wattage, you're just reducing your coverage area. Replacement wasn't bad, you just have to remove to top and the plastic basket, 4 screws, push the tabs down to remove the basket and unclip the clips. My bulb broke in my hand trying to pull it out. I had to use a flat head screwdriver to pry between the base of the bulb and the fixture going around until it came loose.
