Flat art is ideally illuminated by a source striking its surface at a 30 degree
angle. This eliminates veiling reflection (glare) from bouncing into a
viewer's eye, and prevents the casting of a shadow of the viewer
onto the artwork.
To determine the correct distance from the wall you can use the below listed formula or quick reference chart.
Formula to calculate luminaire distance from the wall for a 30 degree aiming angle where H = Distance from the ceiling to the aiming point and D = Distance from the wall to the center of the luminaire. (The aiming point is generally selected at 1/3 down from the top of the picture or object.)
D = H x .5774
Example: D = 4.5' x .5774 = 2.6' or approximately 2'-6"
