A fluorescent bulb, often known as a fluorescent lamp or fluorescent tube, is a low-pressure mercury-vapor fuel discharge lamp that makes use of fluorescence to provide seen gentle. Fluorescent bulbs are extensively utilized in properties, workplaces, and different business buildings as a result of they’re energy-efficient and have an extended lifespan. Nonetheless, fluorescent bulbs can typically malfunction, so you will need to know how you can test them to make sure that they’re working correctly.
There are just a few alternative ways to test a fluorescent bulb. A method is to easily flip it on and see if it lights up. If the bulb doesn’t gentle up, it could be burned out and can must be changed. One other strategy to test a fluorescent bulb is to make use of a multimeter. A multimeter is a tool that may measure electrical present, voltage, and resistance. To make use of a multimeter to test a fluorescent bulb, set the multimeter to the “resistance” setting after which contact the probes to the 2 metallic contacts on the bulb. If the multimeter reads “0” ohms, the bulb is sweet. If the multimeter reads “OL” (open line), the bulb is burned out and can must be changed.
