Abstract
At least one layer of cascading material overlying an EL lamp converts the light emitted by the EL lamp into infrared light. The EL lamp is supported within in a container transparent to at least infrared light, along with at least one battery and an inverter to provide power for the lamp in portable applications. The lamp is rolled to form a cylinder and fits within the inside diameter of the container. The lamp can be turned on or off by means of a switch interrupting current from a battery or to the lamp.
