ABSTRACT:
A testing kit for luminaire lamps includes a shorting cap that is to be substituted for a photoelectric sensing device to test its operability, and a luminaire lamp testing instrument that is to be used while the shorting cap is in place for testing the operation of the starter and the ballast associated with the luminaire. The shorting cap includes a plurality of equidistantly distributed indicating lights to enable the user to see one of them from any angle, a built-in circuit breaker that trips when there is a short circuit downstream from the photoelectric sensing device, and a pair of jacks for connecting a voltmeter thereto. The luminaire lamp testing instrument has an evaluation circuitry that determines whether or not the starter or the ballast function properly and causes either one of two lights, depending on the design wattage of the luminaire lamp, to issue visually distinguishable signals indicative of proper operation of the starter and the ballast, respectively.
