Luminit’s directional turning film (DTF) consists of linear non-symmetric microprisms that deflect a nearly collimated light source by 20°. The direction turning film can be combined with a light shaping diffuser of any angle to simultaneously shape and deflect the beam.
The DTF is ideal for recessed LED lighting such as uplighters, stair lighting, and swimming pool lighting.
