You have to make the distance between lights equal to the distance between the wall and the lights.
Eyeball light distance from wall.
Wall grazing fixtures are designed to graze a textured surface such as stone or brick with light.
This would be width number of lightsin the row or 10 feet 2 lights 5 feet between lights across the width of the room.
Setback distance sd eye height ey x 0 6 setback distance is the distance from the vertical wall surface where the painting or other artwork is hung to the center point of the downlight luminaire.
Both techniques light vertical walls to make a space feel larger brighter.
It is preferred to use awall wash recessed lighting trim which have a directional reflector that focus the light only toward the wall.
The ideal angle to light a picture on the wall is 30 degrees meaning if you tilt an eyeball or adjustable can light 30 degrees to the right or left it lights up the picture at eye level.
Now to get the distance from the wall you can divide the length between the lights in half which would equal 5 feet 2 2 5 feet.
That distance depends on your ceiling height equal to 0 33 of your ceiling height.
Below some tips you keep in mind when you attempt to layout placing and choosing recessed lighting units.
Width of the room you would then apply the formula to the widthof the room.
30 degrees is ideal to minimize glare and reflectance measured at the ceiling from vertical.
Measure the width of the area and write down your answer.
Divide the width of the area by twice 2x the number of lights to be placed in that row and write down your answer.
Do the same calculations for the width rows the width of the area to be illuminated.
Much like the can light eyeball lights are recessed into the ceiling but the interior has a swivel mechanism that allows it to move like an eyeball.
Divider now do the same for the width of the area.
To light an area like fireplace the distance to place the recessed light unit away from the wall should be approximately 60 of the distance from the ceiling to the area you need to light.
The placement of the recessed light in relation to the picture on the wall is what determines the aiming angle.
So remember the distance between your lights is always twice 2x the distance from the wall to the first light.
The distance between the wall and the first light unit is the same as the distance between the wall and the last recessed light unit and is half the space between the recessed light fixtures.
Eye height represents the distance from the ceiling to the point where you typically aim your gaze while looking at the artwork.
