an optional eight-lamp LED lighting system, available in practical white or beautiful cobalt blue, allowing for optimum use day or night. The Berkey's* LED lamps are unique because incredibly, they have an average life of over 11 years of continuous use and are so bright the white LED's can be spotted for more than a mile in the dark, yet they require very little energy. In fact, the low energy LED's are able to provide light, all night long, for over two weeks on a single set of four AA alkaline batteries. That's why the Berkey Light* is the ideal emergency light, camping-light and nightlight. What's more, the detachable base can be used as a stand-alone emergency flashlight.
