An EL lamp includes a strip of EL material within a translucent cylinder, preferably a glass tube. The tube can be frosted or coated to further enhance the appearance of the lamp. The strip can be flat or curved and, in an alternative embodiment of the invention, the lamp includes a glass fiber between the light emitting surface of the strip and the tube for gathering light from the strip and emitting the light in a preferred direction. The tube is an optical element combined with the strip to produce the unexpected result of having the tube appear luminous, even without coatings to enhance this effect.
