         8 . The horticultural light fixture system of  claim 1 , wherein the first and third endcaps comprise hollow channels. 
     
     
         9 . The horticultural light fixture system of  claim 8 , wherein the hollow channels of the first and third endcaps receive the coupling mechanism. 
     
     
         10 . The horticultural light fixture system of  claim 2 , wherein the first and third endcaps comprise hollow channels which receive respective portions of the hinge. 
     
     
         11 . The horticultural light fixture system of  claim 1 , further comprising a power supply cable ( 430 ) adapted to receive power from a power supply ( 420 ), the power supply cable configured to, when energized, supply power to the light sources on the first set of substrates and the second set of substrates. 
     
     
         12 . The horticultural light fixture system of  claim 1 , wherein the first and second positions are displaced relative one another by about 180 degrees. 
     
     
         13 . The horticultural light fixture system of  claim 1 , wherein in the first position the first plurality of light sources is in confronting relationship to the second plurality of light sources. 
     
     
         14 . The horticultural light fixture system of  claim 1 , wherein
 in the first position, light-emitting surfaces of the first plurality of light sources are approximately in confronting relationship to light-emitting surfaces of the second plurality of light sources; and   in the second position, light-emitting surfaces of the first plurality of light sources face in a similar direction to light-emitting surfaces of the second plurality of light sources.   
     
     
         15 . The horticultural light fixture system of  claim 1 , wherein at least one of the endcaps comprises a rail.
