LEIA optics can be used to create very different kind of lighting effects either by itself or by with the additional sublens. It’s an excellent choise for e.g. wall-grazing applications.

VISUALIZATION OF THE BEAM TYPES

LEIA-S: Ideal for wall-grazing on smooth surfaces from a close distance.

LEIA-S with sublens: Ideal for wall-grazing of uneven surfaces from a greater distance.

The lens is slightly tilted inside the holder to make lighting up walls easier. The direction of the beam is indicated with an arrow inside the holder and on the outside on the top flange.
