Floodlights, varychrome

Distance to wall to be between half and full height of the wall:
If the wall height is only half then optimum lighting results by setting the tilt at 35°
For the full height of the wall, optimum lighting results by setting the tilt at 60°

a1 = h/2
a2 = h

To light a large area: luminaire spacing - up to 2x offset from wall

d = 2a

Distance to wall: half the luminaire spacing

c = d/2
