Light layout

[SSStang]

I have a 30x40x12 shop I’m working on I have 9 lights in the link below. What would be the best layout?
No I’m not gonna buy more well maybe one if ten works out better.

To have even lighting throughout your shop, you have to figure out correct spacing. Manufacturers often have a spec for the "cone" of light they put out. It depends on ceiling height too.
Something like
/°\ /°\ /°\
The main thing to keep in mind is the sides or edges are a half a cone, and between the fixtures is both halves of a cone. Your spacing will be 1x/°\2x/°\2x/°\1x where
x = (shop width or length)/(number of fixtures in that row*2).

So working from one end: on the 30 ft side the center of each light will be 5 ft, 10 ft, 10, ft and again 5ft from the end
On the 40 ft side the centers will be 6ft-8in, 13ft-4in, 13ft-4in and again 6ft8 from the end.
That should give you the most even lighting with 9 fixtures

Thank you for the reply. Sorry but maybe I haven't had enough coffee yet but could you break that down little more for me.
How does that equal 9 lights?

From the wall 5 feet, light, 10 feet, light, 10 feet, light, and if you did it right there should be 5 feet to the next wall.

I finished up installing my lights earlier this week. Thanks for the information. I’m pretty impressed on how bright these lights are and I think the layout is perfect.
