Abstract: An adjustable light fixture and lighting system are selectively adjustable in the field and provide even light distribution across a space. A housing is selectively adjustable to a selected housing length and is mountable to the surface. A tray mountable to the housing includes plates which are selectively adjustable relative to one another to a selected tray length. Each plate includes a plurality of electroluminescent light sources providing uniformly luminous light across the light fixture. Overlap of plates varies the tray length and blocks light from light sources on one plate by the opposite plate. Evenly distributed light is therefore provided with no bright or dark spots. A lighting system of a plurality of light fixtures electrically connected to one another includes at least one adjustable light fixture, and preferably at least one stationary light fixture of fixed length. Methods of installation are also disclosed.
