Abstract:
1. A lighting tester for testing one or more types of lamps, the lighting tester comprising: a housing; an antenna coupled to the housing and including a first pull-out shaft and a second pull-out shaft that are pulled out and extended away from the housing of the lighting tester, at least one of the first pull-out shaft and the second pull-out shaft being coated with an electrically insulating material, the first pull-out shaft configured to be in electrical communication with the second pull-out shaft, wherein the first pull-out shaft is the first of the first and second pull-out shafts to be extended from the lighting tester, and the first pull-out shaft is the last of the first and second pull-out shafts to retract into the lighting tester; the housing containing a second test circuit configured to receive a signal associated with a lighting ballast, the signal capable of being received without contacting the lighting ballast, and determine whether the signal is indicative of a high-frequency voltage generated by the lighting ballast, and a third test circuit configured to receive a first terminal and a second terminal of the lamp and test a filament of the lamp for continuity; a worklight configured for use in conjunction with at least one of the first test circuit, the second test circuit, and the third test circuit; and at least one output device configured to provide a signal indicative of the operation of at least one of the first test circuit, the second test circuit, and the third test circuit.
