A combination lighting tester tool. The combination lighting tester tool includes at least three independent testing tools for identifying and diagnosing a problem in a lighting system. For example, the tester includes a lamp testing function in which a high voltage test signal is generated and transmitted using an antenna. When the test signal is in proximity to a gas filled lamp, the voltage is of sufficient magnitude to ionize the gas inside the lamp, causing the lamp to illuminate. The tester also includes a ballast testing function in which the power lines or wires connecting a ballast to a lamp or lighting fixture are tested, and a filament tester for testing the filaments in a lamp for continuity or resistance. The tester also includes a worklight for illuminating an area under test and one or more display devices (e.g., LEDs, an LCD display, or the like) which provide an indication of, for example, a test being performed or a result of a test.
