The LightRail® 3.5 IntelliDrive Kit comes complete with a 10-RPM motor and a two-piece 6.5-foot rail, installation hardware and instructions. LightRail 3.5 travels at 10 RPM (approximately 4 feet per minute) and has a zero-to-sixty-second adjustable time delay for pausing the lamp at the end of each run. This helps promote even growth from end to end and allows for equal light-time for the entire run. LightRail 3.5 will move hoods of multiple sizes and weights and is a scalable system in which up to three lights can move in-line with the use of one motor. Two-year warranty.
