This is the condenser lamphouse for Beseler 4x5 series enlargers, including the 45M, 45MX, 45H, 45AF, 45MX II, 45MXT, and 45V-XL. The Beseler "cone of light" system provides optimum illumination for printing all negative formats up to 4"x 5" without requiring the use of auxiliary condensers. The lamphouse includes the set of 6½" condenser lenses, lamphouse filter tray and filter support panel, condenser position scale ("negative stage indicator"), and 150W PH212 opal enlarging lamp.
These lamphouses are used and have minor cosmetic marks, but are certified to be in perfect working condition.
