1 Buy = 4 Light Rail 4.20 AdjustaDrive Kits to move eight grow lights in total, 2 each. Each Light Rail 4.20 AdjustaDrive Kit is a genuine Light Rail, quality constructed in the USA and made to last and that’s under continuous use. Only Light Rail performs over many years like a workhorse with the power and endurance for any grow light weight. Beware of cheaply made imitations. Details: Light Rail 4.20 AdjustaDrive grow light system with adjustable travel distance, both a 0-60 second adjustable time delay for promoting even growth from end to end plus the added feature of a 2-4 feet per minute adjustable speed control that covers a wide range of grow lamp system intensities and travels distances; each Light Rail 4.20 includes the following: Light Rail 4.0 AdjustaDrive Motor with variable speed, a two piece, 2-meter (6'6") in total Rail, an Add A Lamp Kit with another Rail, an Aux Trolley, push/pull rod, each complete to move two grow lights inline and each on its own Rail.  Light Rail is the only light mover made for continuous duty, will move any grow light weights and it is the single most important way to supercharge our indoor grow light equipment. We get much better yields when our grow lights move because more leaf area is reached with better light, so no hot spots and no shadow patterns. Plus we cover 30 to 50% more area, and that’s per grow light.

Brand matters and LightRail is solidly made in the USA by Gualala Robotics since 1986. Light Rail has a sealed instrument grade drive motor you can count on that runs on only 9 watts, advanced digital control circuitry, Extreme Duty Trolley Wheels rated to 60 lbs as sealed precision bearing carrier wheels, and a self-clutch drive design with automatic traction control. These features are unique to the Light Rail brand. Light Rail is the only brand with authentic electrical certifications C CSA US or CE, and flammability ratings UL 5 VB, and is RoHS compliant. Light Rail is unique as it runs at a safe 85 degrees F with a flame retardant electrical enclosure, as it should be, with the knock-off light movers running at up to 170 degrees F, some even hotter. Solidly constructed and extensively tested, Light Rail 4.20 will move any grow light weight and is an expandable system where up to three grow lights can move in-line with the use of one Motor. Made in America Matters. Smart robotics. You can only get this with Light Rail by Gualala Robotics.
