Lens wallwashers
Outdoors, uniform vertical lighting defines spatial borders. The distance to the wall (a) of Beamer wallwashers should be around one third of the wall height (h) for this purpose. This results in an angle of tilt (γ) of around 55°.
Arrangement: a = 1/3 x h or γ = 55°
For good longitudinal uniformity, the luminaire spacing (d) of Beamer wallwashers may be up to 1.2 times the distance to the wall (a).
Arrangement: d ≤ 1.2 x a
Optimal wall distances and luminaire spacing values for individual products are specified in the wallwasher tables at www.erco.com.
