Removing a stuck recessed light bulb can be uniquely frustrating. Since the light bulb is sunk into the ceiling, it’s difficult, if not impossible, to grip the sides of the bulb. But there are a few simple techniques and free or inexpensive tools you can use to safely remove a stuck recessed light bulb.
Wait until the bulb is cool before removing it. Though removing a stuck recessed light bulb may seem like a safe process, there is a distinct possibility that the bulb may break, sending shards of glass and filament into your eyes. So it’s important to always wear safety glasses.
Do not use lubricants or any type of fluids to remove the recessed light bulb.
