enable uniform illumination of
high walls. The ideal spacing to the
wall (a) is a fifth of the room height
(h).
Arrangement: a = 1/5 x h
Application area: positioned close
to the wall, these luminaires are
ideal for atriums and foyers with
room heights above 6m, but work
just as well in rooms with lower
ceilings.
For wallwashing with good and
uniform horizontal illuminance,
the spacing (d) of double-focus
wallwashers may be up to 1.3 times
the offset from the wall (a).
