Fluorescent light bulbs are a type of electric light bulb that uses a fluorescent coating on the inside of the bulb to produce light. They are more energy-efficient than incandescent light bulbs, and they last longer. However, fluorescent light bulbs contain mercury, which is a hazardous material. It is important to dispose of fluorescent light bulbs properly to avoid environmental contamination.
In most cases, you can remove a fluorescent light bulb by simply twisting it counterclockwise. However, some fluorescent light bulbs have a locking mechanism that prevents them from being removed by hand. If you encounter a fluorescent light bulb with a locking mechanism, you will need to use a pair of pliers to remove it.
