light around a circle

[d1reyad]

How do you place different light around a circle so that each lights are perfectly distributed around the circle i want to know is their is a formula

 

[Dennis Alwon]

I did one a few years back. I took my circumference and divided by the # of fixture-- I beleive

What I've done is the old fasioned way. Tie a pencil to a string and tie the other end of the string to a screw or nail in the middle of the circle. Make the string the desired radius ( 1/2 the total widht of circle), and let the fingers do the walkin : )

So If you had a circumference of 36 feet and you wanted to use 6 cans then you would place one every 6 feet.

I drew a circle on the floor below and layed it out. I then used a laser plumb up to the ceiling.

am not following you on using the diameter i dont even know what that is

Use the circumference-- I edited my post. The circumference is the distance around the circle.

 

[d1reyad]

so you find the circumference and multiply the numbers of light

How many lights?
How big is the circle?

Interesting picture Dennis, I assume the high cove was back light as well,
I noted they changed the direction of ceiling vents Nice Job!

divide by the # of lights. Read my example in post above. 6 fixtures with 36 foot circumference-- 36 divided by 6 = 6 feet apart.

Thanks, Yes there is rope lighting in the cove inside the circle. It came out real nice. I spent many hours on that with the framing etc. I determined the # of cans so as to avoid any framing changes-- we did have 2 areas to reframe. The floor was also 2 level-- step up so laying it out was not so easy. :smile:

Try doing an arc, with a 135' radius...... (top center of photo)::wink:

The only thing wrong with Dennis's pic is that he wasted all that #12 for lighting. :wink:

Showoff. :roll:

Yeah, should've use #14.

You mean you didnt just scale off the print?

Actually, no, they didn't. The pictures were taken from different directions.

The circuit was part of a homeworks system and the loads were such that I had to use #12. Not my choice for lighting but it was designed by another party who was providing the system. Most of the lighting in the house was #14 for lighting ( over 200 cans- half low voltage)

Nice job!

Looks like a bit of a pain to lay out though.... :grin:

To find the circumference (distance around a circle), multiply the diameter (the distance across the circle) by "Pi" which is 3.14159265 (3.14 will usually get you close enough). then you can divide that distance by the number of fixtures.
