EXCELLENT UNIFORMITY To meet the stringent standards of vertical illuminance, ERCO has developed luminaires specifically to produce exceptionally uniform levels of illuminance. LARGE LUMINAIRE SPACING FOR WALLWASHING For some wallwashers, the luminaire spacing may be up to 1.5 times the offset from the wall. Appropriate details are provided in the wallwasher tables in the catalogue or the product data sheets. Computerised beam calculations are recommended to check potential intersections with side walls. ENHANCED VISUAL COMFORT ERCO has developed luminaires with special housing designs and high-quality optical components -specifically for demanding visual tasks to provide enhanced visual comfort. AVAILABLE IN ROUND OR SQUARE The ERCO system design includes round and square versions to provide luminaires suited to the architecture and surroundings. SMALL LUMINAIRE DIMENSIONS Available in the new sizes 3 and 4, the Tesis in-ground luminaires can now be even more inconspicuous in their surroundings directing the focus onto the light, not the luminaires. Tesis has long been a regular feature in the outdoor range. In a completely upgraded version, it now delivers an entirely new level of performance. Innovative photometrics ensure maximum brilliance and efficiency. A considerably flatter housing thanks to LED technology ensures exceptionally straightforward installation - in both round and square version. The robust polymer housing is fully corrosion-resistant and designed to ensure long life and ease of use. Be it directional luminaire, uplight or wallwasher, Tesis sets the benchmark in outdoor lighting. LUMINAIRE ARRANGEMENT LENS WALLWASHERS Uniform vertical illuminance in the outdoor area defines spatial borders. Here, the distance (a) of Tesis lens wallwashers from the wall should be around one third of the room height (h). ARRANGEMENT a = 1/3 x h For good longitudinal uniformity, the spacing (d) of round Tesis lens wallwashers may be up to 1.3 times the offset from the wall (a). ARRANGEMENT d ≤ 1.3 x a The optimal wall offset and luminaire spacing for each product are indicated in the wallwasher tables in the catalogue and the product data sheets.
