Did you know_ Stationary lighting only shines light on the parts of leaves that are directly beneath it, which can cause limited growth and even damage to the plant similar to sunburn. LightRail solves this problem by moving over the tops of plants, so that the leaves get light at different angles, activating photosynthesis on parts of the plant that would not normally receive much light with a stationary system.

With stationary light, light energy can also be lost because it cannot diversify itself in order to allow your plant to absorb it at the optimum levels. LightRail shines the correct intensity of light on the leaves for 40% of the photoperiod. This allows the plant to reach optimum Leaf Area Index, the most important factor in increasing yield. Also, by moving your light, you can now safely get your light closer to your plants for a more efficient use of the wattage available.

LightRail is the single best way to maximize your light set up. Solidly made in the USA since 1986, LightRail 4.0 is the light mover of choice with an instrument grade drive motor that runs on only 9 watts, digital control circuitry, heavy duty ball bearing carrier wheels and a self-clutch drive design with automatic traction control. Manufactured by Gualala Robotics, LightRail has all the electrical certifications (C CSA US and CE) and flammability ratings (UL 5 VB) and is RoHS compliant. LightRail has a two year manufacturer warranty, runs at a safe 28-42 degrees C with a flame retardant electrical enclosure, as it should be, while imitator light movers run as hot as 107 C (170 F) and their electrical enclosures are likely made of flammable plastic. Without quality, there is no value and if it does not say Gualala Robotics, it is not a LightRail.

Light Rail 4.0 AdjustaDrive Complete Kit (Two 3' Rails) Questions & Answers

How much weight will LightRail Carrry?

The answer to this is twofold. For LightRail 3.5 and 4.0 let’s first talk about the strength of the rail then we’ll talk about LightRail Drive Motor that moves your grow light. If only mounted by the mounting holes at the ends of the rail, the rail will begin to deflect when 35 lbs. (16kg) is in the middle of the rail. If all the rails mounting holes are used when mounting the rail first to a board, and then the board to the structure above your garden, it will easily handle 75 lbs.

Next, the LightRail 3.5 or 4.0 Drive Motor can easily move 75 lbs (34kg). However, more weight equals accelerated wear and tear mostly on the Trolley Wheels. LightRail's testing has shown that the Trolley Wheels on a LightRail 3.5 or 4.0 Drive Motor will last between 12 and 16 months moving a load of 35 pounds (16kg). Their Extreme Duty Trolley Wheels have a lifetime warranty at 60 pounds per set of four. Plus they have very low drag co-efficiency so they are the best choice for moving heavy or multiple reflectors

LightRail 5.0 will hold and move 100 lbs (45kgs) per cross arm (limit 3 cross arms) but again, needs to be mounted to a structure properly. Note: The greater the weight, the more frequently trolley wheels will need to be replaced. Trolley wheel kits are available for LightRail 3.5, 4.0 and the older 3.0, but for LightRail 5.0 needs LightRail must be contacted for any serviceable work and they make that easy and with a quick turnaround time.

What's the difference between the Light Rail 3.5 and 4.0?
They both have 0-60 second adjustable time delay for the ends and they have the same rail but the 4.0 has the added feature of a two to four feet (.6 to 1.2 meters) per minute adjustable speed control as it travels along the rail. The 3.5 and 4.0 are compatible with using all the same accessory items including drive wheels and trolley wheels.


Light Rail 4.0 AdjustaDrive Complete Kit (Two 3' Rails) Reviews

PS 1000
This mover has lived up to my expectations. I run a Perfect Sun 1000 and the coverage I get with the 4.0 is fantastic.

Light rail
These things are the sh@. I have a kind led (about 30lbs), and handles the weight, no problem. Instead of 4 watt sucking lights, I run 2 and no a/c is needed now. Great product
