Constructed of stainless steel, these light boxes offer a comfortably slanted surface for more convienient viewing and tracing. The transluscent surface is flush-mounted for a clean, unobstructed flat work surface. Accurate 90 degree edges offer precise reference for measuring and attaching T-squares. The illumination is a combination of daylight fluorescent lamps and a specially designed polyester pearlescent reflector system. This 16" x 18" box takes three 15 watt, 18" fluorescent replacement lamps.
