Improved visual comfortERCO has developed luminaireswith special housing designs andhighquality optical componentsspecifically for demanding visualtasks to provide enhanced visualcomfort.

Outstanding uniformityTo meet the stringent standardsof vertical illuminance, ERCO hasdeveloped luminaires specificallyto produce exceptionally uniformlevels of illuminance.

Available in round or squareThe ERCO system design includesround and square versions toprovide luminaires suited to thearchitecture and surroundings.

Large luminaire spacingFor some wallwashers, the lumin-aire spacing may be up to 1.5 timesthe offset from the wall. Corres-ponding details are provided in thewallwasher tables in the catalogueor the product data sheets. Com-puterised beam calculations arerecommended to check potentialintersections with side walls.

Lens wallwashersWallwash

WallwashingUniform vertical illuminance inthe outdoor area defines spatialborders. Here, the distance (a) ofTesis lens wallwashers from thewall should be around one third ofthe room height (h).

Arrangement: a = 1/3 x h

For good longitudinal uniformity,the spacing (d) of round Tesis lenswallwashers may be up to 1.3 timesthe offset from the wall (a).

Arrangement: d ≤ 1.3 x a

The optimal wall offset and lumin-aire spacing for each product areindicated in the wallwasher tablesin the catalogue and the productdata sheets.

UplightsWide flood

AccentuationTesis uplights used for the accen-tuation of objects such as treetopsor cantilever roofs need to beaccurately positioned and alignedto ensure that the light arrivesprecisely and only on the targetsurface to avoid light pollution.

α

AccentuationExperience has shown the idealangle of tilt (a) for accent lightingwith Tesis directional luminairesto be 25°. This ensures good mod-elling without excessive grazinglight.
