The Spectroline 36-380 pencil lamp is one of the smallest sources available of filtered, long wave ultraviolet (Black Light) radiation. It is basically the 11SC-1 lamp coated with conversion phosphors that absorb the 254nm line and convert this energy into a band peaking at 365nm. The lamp is encased in a tubular glass filter that absorbs visible light while transmitting maximum ultraviolet intensity. The 36-380 lamp is ideal for fluorescent penetrant analysis and boroscopic inspection in ordinarily inaccessible locations.

SCT-1A Power Supply

The separately housed Spectroline SCT-1A power supply provides correct electrical characteristics for efficient operation of the 11SC-1, 11SC-2 and 36-380 lamps. The SCT-1A provides 1,200 volts open circuit for starting the lamps — considerably above the 800 volts needed. The 11SC-1 and 36-380 will operate at 295 volts and 18mA; the 11SC-2 will operate at 205 volts and 18.5mA.
