  • Vertically adjustable overhead lighting system
    Patent number: 6312139
    Abstract: An apparatus used to deliver light from overhead to stimulate plant growth in a controlled environment. The distance between tops of the plants and the lights can be adjusted to correlate with plant growth by a motorized assembly for raising and lowering a bar suspended from an upper support and upon which are mounted growth lights. Horizontal sway of the bar upon which the growth lights are mounted is minimized by a guiding structure for one end of the bar. When florescent growth lights are used, bulk and heat produced by their ballasts are eliminated by locating all ballasts remotely from the apparatus.
