By moving a lamp on an approximately 2.2 m long track of the illumination area is increased by a multiple. This means lower operating costs due to better yields when using a single lamp. Come 2m rail (in two matable pieces meters), the drive and power supply + 2 Stopper + mounting hardware (screws, ect.) On the rails, stoppers are placed so that you are completely free to choose the route to be. The Intelli Drive method allows stopping times between 0-60 seconds on each end of the rail. So the drive the lamp moves continuously back and forth. The plants are illuminated better with the Light Rail, there are fewer shaded areas in the greenhouse
