Abstract: An apparatus that prevents the interchange or replacement of an expensive compact fluorescent lamp with a standard inexpensive incandescent bulb to diminish thefts of the more expensive lamp, by using a locking lamp socket insert in combination with newly designed screw lamp base that permits the operation of the compact fluorescent lamp. Should the compact fluorescent lamp be substituted with a standard inexpensive incandescent bulb, the center contact in the base of the incandescent bulb cannot touch the centrally located leaf-spring contact of the lamp socket, thereby preventing the incandescent bulb from operating.
