Testing a fluorescent bulb is a simple process that can help you determine if the bulb is still functioning properly. Fluorescent bulbs are a type of lighting that uses electricity to excite mercury vapor, which then produces ultraviolet light. The ultraviolet light is then converted to visible light by a phosphor coating on the inside of the bulb. Over time, the phosphor coating can degrade, which can lead to a decrease in light output and an increase in energy consumption.
There are a few different ways to test a fluorescent bulb. One way is to simply turn the bulb on and off. If the bulb does not light up, then it is likely that the bulb is burned out and needs to be replaced. Another way to test a fluorescent bulb is to use a multimeter. A multimeter is a device that can measure electrical current, voltage, and resistance. To test a fluorescent bulb with a multimeter, first set the multimeter to the ohms setting. Then, touch the probes of the multimeter to the two metal contacts on the base of the bulb. If the multimeter reads a resistance of less than 1 ohm, then the bulb is good. If the multimeter reads a resistance of infinity, then the bulb is burned out and needs to be replaced.
