Abstract
An illumination device, including: a shell with a plurality of sides, where the device can be positioned upon a surface or attached or suspended at any of the plurality of sides; and at least one light-emitting device within the shell, where when the device is positioned upon a surface or attached or suspended at any of the plurality of sides of the shell, light from the at least one light-emitting device emits through each of the plurality of sides of the shell. The device is thus easy to deploy and use. Its design is compatible with outsourced manufacturing, allowing for cost savings. The device can be reused many times. The device can also emit light for many hours longer and has ruggedness that far exceeds conventional devices. The device can also be used where conventional devices and other lighting devices cannot, including underwater.
