The Light Rail brand because?. Only Light Rail performs over many years like a workhorse with the power and endurance for any light at any weight. Beware of cheaply made imitations. Genuine Light Rail, solidly made in the USA since 1986. Manufactured by Gualala Robotics so always in stock and typically ships same day. Built to move 2 grow lights side by side, the Kit includes a high torque 4rpm instrument grade drive Motor with ball bearing output shaft and ?sure grip? dual drive design, two piece 8 ft in total Rail, crossbar, aux trolley, hdw and instr, adjustable settings for travel distance and with a 0 to 60 second adjustable time delay. Light Rail 5.0 works with 110v, North America compatible. Authentic electrical ratings are earned, and Light Rail has these electrical certifications C CSA US or CE, and flammability ratings UL 5 VB, and is RoHS compliant. Light Rail runs at a safe 85 degrees F with a flame retardant electrical enclosure, as it should be, and these are safety standards unique to the Light Rail brand. Keep it Real, Keep it Light Rail. A real Light Rail will never have a cover hiding the Motor/Gearbox. That?s because we?re proud of our technology, producing the only light mover with nothing to hide. The Light Rail 5.0 Kit can move multiple crossbars, with each crossbar allowing grow lights to travel side by side Includes a 0 to 60 second adjustable time delay for pausing the grow lights at the end of each run and adjustable travel distance. The time delay helps promote even indoor plant growth from end to end and allows for equal grow light-time for the entire run. From its triple duty extruded aluminum track, wide and stable carriage with steel -on-steel carrier bearings to the high torque 4rpm instrument grade drive motor with ball bearing output shaft and ?sure grip? dual drive design, LightRail 5.0 is more than capable of moving 2 or 3 indoor grow lights side by side, or fore and aft, per crossbar. The LightRail 5.0 Kit comes with a LightRail 5.0 Drive Motor, one crossbar with width-span adjustable settings of 81?, 87? or 93?, instructions, mounting hardware and a 2-piece, 8? (2.4 meters) total length Rail, so it?s long enough and ready for an extra Add-A-Bar Kit to purchase as a second crossbar. LightRail 5.0 will move up to 9 smaller lights, or 6 lights of average size with a single Motor. See photos. Note: With LightRail 5.0, perfect balance is key and vent tubing can play havoc with that. We recommend that if you do have vented hoods, you use LightRail 3.5, 4.0 or 4.20. And, with larger LED grow lights it is recommended to use individual LightRail 3.5 Kits or individual LightRail 4.0 Kits, paired with the new Robo Bar for grow lamp stabilizing. Brand matters and LightRail is solidly made in the USA by Gualala Robotics since 1986. LightRail has an instrument grade drive motor you can count on that runs on only 5 or 9 watts, digital control circuitry, heavy duty ball bearing carrier wheels and a self clutch drive design with automatic traction control. These features are unique to the LightRail brand. LightRail is the only brand with authentic electrical certifications of C CSA US or CE and flammability ratings UL 5 VB and is RoHS compliant. LightRail 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, LightRail will move any grow light weight. Free Shipping rates apply to the lower 48 contiguous states.
