I have just build a Morton horse arena that is 200 x 72 x 16 and it will need lighting.  It has to have "sufficient" lighting but now so bright as a manuactoring plant.  Floor is clay and sand.  Roof is gray insulation.  Side walls are white.  What do you suggest?

Hi Steven,

Thank you for contacting us!

I did a sample layout, and a 3 x 5 pattern would look great. 

This is using our American made product, TechBrite 6 Lamp T5HO fluorescent high bay, shown here: http://www.prolighting.com/6lat5flhibay.html , mounted directly to the bottom of your trusses. You can also suspend them using our aircraft cable kits: http://www.prolighting.com/gr60ytohakit.html .

Let us know if you have any questions or comments.

Thanks again,
