The sweetest industrial lamp I have ever seen ! It is not a production model and looks as if it was made in a machine shop for a specific purpose in that shop because it is extremely heavy. The turn key buckle on the shaft allows the lamp to swivel 360 degrees and the hood will cant 45 degrees in two directions - it can be adjusted to a total height of 39 inches and lowered substantially by allowing the floating arm to swing past it's base and off the surface where the base is resting. It retains it's original GE switch and heavy duty wiring.
