Famous Liter Of Light Solar Led References. Web liter of light is a global, grassroots movement that uses inexpensive, readily available materials to provide high quality solar lighting to people with limited or no access to electricity. Web luminance (l v) is the luminous flux (φ e) of visible light emitted by the given surface of an led, per unit solid angle per unit projected area, measured in lumens per steradian per square meter (lm/sr/m 2) or candelas per square meter (cd/m 2).

The resulting device can provide up to ten hours of light when fully charged by sunlight.
