actually yes they do its called light rail 3.5 i have one i just picked up it mounts to the ceiling and u put it on a timer the lights are on and you put it on the speed you want and it goes back and forth across the rail mines a 6ft rail and it takes 10-13min to reach each end of the track and u can set how far you want it to travel the track each way then you can get the trolly add on where u can hold 2 lights and fans so u can blow air to strengthen the roots and stems. There about $199-$249 depending on what length and how much weight it will hold heres the link http://www.homeharvest.com/lightmovers.htmnobody has made one of these? Really?

if you want it to work in a small room your can cut down the track to your specific length and then put the motor on a plug in dimmer switch to drop the amperage and it will slow down the motor even more so it barely moves then adjust your stops accordingly u can make the light track move 2 inchs both ways if u wanted just the motor would change directions to much because the speed this is where the plug in dimmer switch would come into play where u could lower the amperage even more to slow the rpms down even further
