The present invention is a modular indoor farm lighting system. The lighting system is comprised of a frame comprising two or more retaining members and one or more support members. The retaining members are adapted to retain corrugated panels. The corrugated panels have light emitting diode (LED) bars disposed within their troughs. Each LED bar will be provided onto a combiner board. The combiner boards will provide each LED bar with power, and hold 4 LED bars in the preferred embodiment. The system may be hung by a carabiner and rope system to be attached to the vertical components of the support members.
