Help needed on Light-Mover Project *Please*

 Does anyone fancy helping me build a Light-mover?


I have tried for some time to locate specific product parts to no avail.


What I need is help in locating the T-rail and an appropriate low-voltage motor to move the lights along the T-rail - I'm hoping the combined expertise and resources here might help me achieve my goal.


Essentially, for those that don't know, a Light-mover is a bar that automatically moves a light back and forth along the bar so that the same light covers a greater area; it also helps with minimising light-heat in the one spot as well as eliminating a lot of permanent shadows from a static light.


For starters, I need to locate a T-bar - I have tried metal distributors with no luck and I also need a high torque, low voltage  motor - all products to be based in the UK if possible.


I will put the finished project in my greenhouse in the garden.


Many thanks

No worries, glad to help.

I'm not sure what sort of T-bar you require in regards to it's design, do you want it just as a basic T or have some sort of extra motor guide in it - would this one do per chance?

 Thanks for that, Peat. The

 Thanks for that, Peat.

The idea of making one myself is to avoid the high cost (well, it's high to me) and also to over-engineer the specs (the motor particularly, as I have seen several posts stating that motors have had to be replaced at about 60% of the original cost).

I have everything sorted, from the electrics to the stop-and-reverse, but not the actual T-bar or motor - I'll have a look as you suggest.


As I woke up this morning and thought about this post, it occurred to me how selfish I was to ask for help with nothing in return. To remedy this, should I finish this project I shall put the process here so that others here might do the same thing for themselves - entirely at their own risk, of course! 


Well, thanks to Peat, I found just the motor I think I need. I'll send off for it at the end of the month - and now I shall re-double my efforts to find the T-bar. Thanks you, Peat!

There are a number of UK

There are a number of UK sites which do the complete kit you're after, I came across one for £155 which included everything you need.

I guess it depends on if you want to get an off-the-shelf unit or create a project to build one yourself.

It's not only the motor you need, a way of controlling it's speed (unless you get a specific, fixed, RPM motor that will accommodate your run), and, reversing the direction of travel once it reaches the end stops is necessary - unless it's a circular route of course...

There are plenty of hi-torque/low RPM motors on the internet, go for a Google on "60rpm high torque motor".

Apologies if you have already considered any of this, I'm just throwing some thoughts out as they come into my head.
