Luminescent Torch

An electro-luminescent sheet (ELS) is capable of emitting an appreciable amount of very cool, white light. These devices come in a variety of colours including white, and can be cut to shape or curved. A standard 5 cm by 6 cm sheet manufactured by Seikosha emits 1.5 candelas (blue-green emits 2.2 candelas). This is sufficient for reading at night, or to light a pathway (albeit dimly), or to take in a room at a glance.
