Knox Acculight Light Box for viewing slides, negative film, transparencies, and x-rays. Excellent condition (like new).
Metal body. Fluorescent light. 17x13 viewable area. Overall 18x15 inches x 4" high at the back (3" at the front).
Power cord and vinyl cover included. It probably goes without saying but the light is calibrated for optimal color balance. Same item goes for $75 on eBay.
