Perfectly uniform lighting can give walls an almost immaterial quality - even more so when the light source is hidden as discreetly as possible. Such lightingdesign concepts, which ERCO developed for indoor areas a long time ago, can also be applied outdoors with Paratec wallwashers. This range of luminaires with their cast aluminium housings rated IP65 are also suitable for use in indoor areas that are particularly subject to dust or moisture, e. g. swimming pools, wellness centres or historic buildings.

Paratec wallwashers have the same highly asymmetric light distribution as the Parscoop. The difference is that Paratec wallwashers are installed in walls or ceilings.
