I am planning to fit 2 rows of 10 tilting halogen flush fitting ceiling lights. There are two types that I am interested in. One model can tilt
20 degrees while the other can tilt 30 degrees. I will be using the lights to point at pictures on 2 walls. The top of the pictures will be 600mm from the ceiling. I am thinking for maximum effect that the lights should be set around 250mm out from the wall. Does this seem right and are there any websites that have calculations about the placement of tilting flush fitting lighting?
Many thanks
