Illumination from side pin projection lamps in this stand.ard is typically measured using large screen photometry appraisal with lamps placed in aperture and lens systems that simulate projectors. See Figure

Light from lamps converges and passes through a vertical rectangular aperture and projection lens, and is formed into a vertical rectangular image approximately proportional in size to the aperture.
