A modular lighting system that includes or more luminaires that can be individually suspended from a surface or connected to each other to form a variety of scalable arrangements that project light downwardly therefrom. The luminaire can includes a housing that has a first and a second sidewall that is spaced from the first sidewall and a light source that is arranged between the first sidewall and the second sidewall. A first connector can be fixed to and delimit a first end of the luminaire and deliver power to the light source and a second connector can be configured to be fixed to and delimit a second end of the luminaire.
