Testing a fluorescent bulb is a straightforward course of that may make it easier to decide if the bulb continues to be functioning correctly. Fluorescent bulbs are a kind of lighting that makes use of electrical energy to excite mercury vapor, which then produces ultraviolet gentle. The ultraviolet gentle is then transformed to seen gentle by a phosphor coating on the within of the bulb. Over time, the phosphor coating can degrade, which might result in a lower in gentle output and a rise in power consumption.
There are a number of other ways to check a fluorescent bulb. A method is to easily flip the bulb on and off. If the bulb doesn’t gentle up, then it’s possible that the bulb is burned out and must be changed. One other approach to take a look at a fluorescent bulb is to make use of a multimeter. A multimeter is a tool that may measure electrical present, voltage, and resistance. To check a fluorescent bulb with a multimeter, first set the multimeter to the ohms setting. Then, contact the probes of the multimeter to the 2 steel contacts on the bottom of the bulb. If the multimeter reads a resistance of lower than 1 ohm, then the bulb is sweet. If the multimeter reads a resistance of infinity, then the bulb is burned out and must be changed.
