This restored ceiling-mounted Operay Multibeam Surgical Light by Kurt Wehrmann of Northern Scientific is made of aluminum, brass, copper, bronze and steel. This vintage O.R. light is one of the first explosion proof “shadowless” surgical lights made for the surgical infirmary, or operating theater of its time. In present day, one can’t help but think of this retro style steampunk surgical light as something out of a science fiction or Frankenstein horror movie.
For aesthetic purposes I exposed soft metals such as copper, bronze, brass, and aluminum. The gold metallic paint closely resembles that of the original color. It is worth noting that this later model has ridged magnifying glass, as compared to the earlier models which are clear.
This particular model of the Operay Multibeam consists of a central light-emitting orb which is rated for one 200 watt lamp. Inside this orb are six, three inch concave mirrors which reflect the light through seven convex ridged lenses. These lenses magnify the light, where it is then reflected off six eight inch remotely mounted mirrors. The reflected light reduces the interference of shadows during surgery. Focus control is operated by turning an aluminum knob which extends down from a gear box located near the copper counter weight. By turning the knob either clockwise or counter clockwise the surgical staff can adjust the tilt of the mirrors and orb. Depth of field adjustment is made by lifting or lowering the copper counter weight. Lateral tilt can also be achieved by adjusting the friction tension located within a centrally located knuckle consisting of aluminum and brass fittings. Horizontal 360 degree movement is also possible via two separate electrical brush cylinders which allows for a greater range of movement.
This vintage lighting fixture is not meant for professional use, and should only be used for display or recreational purposes. For example, office display, a Woman or Man cave, pool table, or reading light.
