A lamp system is for use in non-destructive testing to illuminate luminescent materials, such as fluorescent dyes. The lamp system has a control unit and a lamp. The lamp has a bulb and a filter. The bulb generates at least a first wavelength of invisible energy and the filter limits other visible wavelength light from the lamp. The lamp has a handle with a trigger. The control unit pulses the lamp on and off when the trigger is depressed. The luminescent material absorbs the first wavelength of energy and pulses in response when the lamp illuminates the material. The system can be AC or DC operated. It can be operated from an automotive battery.

[ We claim:] [1.] A hand held lamp system for locating faults using luminescent material that absorbs ultraviolet electromagnetic radiation of a first wavelength, converts that energy and emits a second visible wavelength light, the system comprising:a lamp for generating incident ultraviolet electromagnetic radiation of the first wavelength;a bulb in the lamp, the bulb generating ultraviolet electromagnetic radiation, including radiation of the first wavelength and other wavelengths, and generating visible light; anda control unit for repeatedly pulsing the bulb on and off at a pulse repetition frequency of substantially 0.5 Hz to less than 3 Hz, and with a bulb on duration which is long enough for the material to begin emitting the second wavelength, and with a bulb off duration which is long enough for the material to substantially stop emitting the second wavelength, the pulse repetition frequency, the bulb on duration and the bulb off duration all timed for the human eye to recognize the pulse of second wavelength light.
