All aspects of the system are covered including ballasts, ignitors, starters, capacitors, and resistors for the following types of light: High and low pressure sodium, metal halide, neon, mercury vapor, and fluorescent. High intensity discharge (HID) fixture testers; both medium E26 E27 and mogul E39 E40 - based fixtures can be tested to check starting pulse voltage and open circuit voltage. Check forward & reverse diode bias, low pressure sodium vapor, and individual procedures for testing fluorescent ballasts. Test light bulbs as well as ballasts.http://www.mitchellinstrument.com/electrical-test-and-measurement/lighting-tester.html
