Abstract
A conductive shield for surrounding a high efficiency light bulb such as a spiral fluorescent bulb is described. A conductive curtain having apertures through which light may pass is connected to the threaded grounded base of the bulb. The apertures in the curtain present high impedance to stray electrical energy (SEE) from the bulb thereby reducing SEE.
