The Landers closely represents an early 1900 fan design. The original fans seldom had a light. I especially like this design as the motor housing looks very realistic and there is more detail to the arms supporting the five blades. Installs with your regular 12 volt system; minimal additional wiring is needed for the working part of the fan. Instructions are included. Fan speed is adjustable. Size: The blade diameter is 3.625 and .82" in height.
