Abstract
The spotlight to be described includes many features which are the result of an extensive investigation of desirable characteristics in such devices. An integral transformer supplies low-voltage alternating current to the arc from any 115-volt, alternating-current outlet at a drain of only 10 amperes. A double-element variable-focus optical system allows the spot size to be continuously adjusted with negligible light loss.
