A linearly extensible modular luminaire comprised of mounting tracks ( 100,180 ) and translationally offset overlapping channels ( 211,212 ), with incorporated luminous means, alone or along with hangers ( 331,332,731 ) that provide support for cover brackets ( 431,731 ) that are attached to light modifying coverings ( 400,900 ), and wherein linearly radiated light is distributed directly, or in combination with coverings indirectly or modified, when connected with a source of power and energized. Also, the modular luminaire that is not extensible but otherwise comprised of same components not translationally offset, permitting the construction of a wide variety of luminaires, such as the one in FIG. 11 , that incorporates a canopy ( 150 ) for mounting over lighting outlet boxes.
