Testing a fluorescent tube is a relatively easy procedure that can be done without professional help. Yellow or blue wires are the power wires, while white indicates neutrality. The process that occurs inside a fluorescent light involves molecules of mercury gas being heated by electricity and made more conductive. Pull the U-shaped bulbs from the tension springs to release them from the socket. Most After completing all the tests on the transformer’s high voltage side, you need the transformer’s low voltage side. You could set up a test rig for tubes, but it would be little more than a fluorescent light fixture on a bench. Without a Ballast also the light won’t start as it provides the higher voltage to the light to start. In the case of fluorescent ballasts, the case must be grounded either to the fluorescent fixture or, if remote mounted, by other means such as a wire from ballast case to ground. To test the fluorescent light ballast, turn off the circuit breaker for the fluorescent fixture, and remove the fixture's lens cover.
