Abstract
Abstract An extension lamp bulb guard and reflector of the type comprising a drop light, which includes a lamp bulb guard or cage unit and a suspension hook operatively associated with a handle and having a lamp bulb reflector. The hook is attached to a handle as a unit, and the reflector is mounted for independent rotation with respect to the unit. The unit consisting of the handle, guard, and hook, together with the associated extension cord, can be suspended from the hook, and regardless of stresses, tensions or torques on the cord, the reflector can be freely turned to focus the light on the work and out of a user''s eyes, without the necessity of loosening or rearranging any parts with the exception of a free rotation or movement of the reflector.
