1. A plant growth lighting system comprising:
a. a plant support configured to support one or more plants;
b. a lighting module comprising a light emitting element (LEE), a light guide having a first end and a second end, the light guide arranged to receive light from the LEE at the first end and configured to guide the received light along a first direction to the second end, and an extractor having an input end and an output end, the input end arranged to receive light from the second end of the light guide and the extractor configured to output light from the lighting module through the output end; and
c. a reflector module arranged to receive at least a portion of light output by the extractor and reflect the light towards the plant support,
wherein the light reflected from the reflector module towards the plant support has a light distribution that is uniform along an optical axis of the lighting module corresponding to the first direction.
