An illumination module is disclosed, which is comprised of a plurality of light sources, a plurality of light source substrates of high thermal conductivity, and a reflecting member for reflecting light. The data storage device has sliding members at opposite sides thereof. The rod end tubes are comprised of sections which allow them to be assembled or disassembled in a close quarters environment. The invention enables the use of stroboscope lamps in commercially available microscopes, which otherwise are not suitable for stroboscopic examinations. The non-volatile storage elements being programmed to the third VTH distribution are specially identified and tracked. After severing, the muntin bar is engaged by a conveyor and moved to a desired location.
