In the movie on netflix Leaves Of Grass about 32 minutes into the video, bulgur raises the all the lights in the grow room with just one switch, how could that be done? another question what are those big silver looking tubes connected to the lights?
the switch is probably hooked to a motor that's on a pulley system. this could be done by reversing the current to the motor.(up one way down the other). as for the tubes on the lights there probably air ducts for a closed air system this takes the heat straight out he room.
