The 4.5 series baby zoom ellipsoidal is a unique luminaire with professional qualities unequaled in other 4.5? spotlights. The smooth operating, variable focus lens system produces wide-to-narrow beams that are uniform and sharp edged with minimal halation. The fixtures are provided with an adjustable lamp holder allowing peak center performance or a flat field when pattern projection is desired. Four adjustable, cool touch, integral stainless steel shutters provide beam shaping ability. The pattern slot and optional holder provide the ability to project visual images, as well as reduce beam diameter zoom ranges with optional circle templates.
