Various changes and alterations might be made in the general form and arrangement of parts described, without departing from the invention. Hence I do not wish to limit myself to the details set forth, but shall consider myself at liberty to make such changes and alterations as fairly fall Within the spirit and scope of the appended claims.

I claim- 1. A portable lamp including a lamp socket, a supporting rame for the socket, suction cups at the ends of the frame, magnetic wall engaging means at the ends of the frame, said suction cups and magnetic means being telescopically adjustable relative to each other, whereby either the suction cups or the magnetic means may be used for supporting the lamp.

2. A portable lamp including a lamp socket, a U-shaped frame, to the intermediate portion of which the socket is secured,

magnetic feet adjustable on the legs of the frame, suction cups encircling the legs of the .frame, and means for establishing a magnetic circuit through the frame.

3. A portable lamp including a lamp socket, a U- haped frame, to the intermediate portion of which the socket is secured, magnetic feet adjustable on the legs of the frame, suction cups encircling the legs of the frame, means for establishing a magnetic circuit through the frame, said magnetic feet being formed with sleeve portions screw-threadedly adjustable on the legs, whereby the feet may be projected beyond the plane of the suction cups, or may be retracted into the suction cups.

4. A portable lamp structure including a U-shaped frame, means for mounting a lamp on said frame, magnetic feet adjustable on the legs of the frame, suction cups encircling the feet, and Within which the feet are adapted to be retracted, and an energizing coil for establishing a magnetic circuit through the frame.
