I just set up a penetrant line at my employer. Along with the system purchase, came a Spectroline Model BIB-150P 120v 60Hz blacklight. Initial check of the intensity was over 5,000 microwatts, since then the intensity has fallen of to about 2,200 in a day. The seems rather dramatic given the projected service life of the bulb. Any suggestions?
Also can anyone suggest a better blacklight?
