Tesis. The benchmark in the outdoor area

An innovative archetype in outdoor lighting

Show products

Special features of Tesis
View product description

Improved visual comfort

ERCO has developed luminaires with special housing designs and highquality optical components specifically for demanding visual tasks to provide enhanced visual comfort.

Outstanding 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 some wallwashers, the luminaire spacing may be up to 1.5 times the offset from the wall. Corresponding details are provided in the wallwasher tables in the catalog or the product data sheets. Computerized beam calculations are recommended to check potential intersections with side walls.

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. 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.

Tesis: Light effect and planning aid

Vertical illuminance for brightening the surroundings and segmenting the exterior landscape.

Lighting technology
Luminaire arrangement

Lens wallwashers

Asymmetrical light distribution for highly uniform wallwashing.

Light source
3.1W - 32.3W
335lm - 4192lm
Lens wallwashers

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.

Uplights

Very wide beam, rotationally symmetrical light distribution for accent lighting.

Light source
3.1W - 24.3W
335lm - 3144lm
Uplights

Uplights

Tesis uplights used for the accentuation of objects such as treetops or cantilever roofs need to be accurately positioned and aligned to ensure that the light arrives precisely and only on the target surface to avoid light pollution.

Directional luminaires

Very narrow to wide beam, rotationally or axially symmetrical light distribution for accent lighting.

Light source
2W - 18.2W
239lm - 2358lm
Directional luminaires

Directional luminaires

Experience has shown the ideal angle of tilt (a) for accent lighting with Tesis directional luminaires to be 25°. This ensures good modeling without excessive grazing light.

Arrangement: α = 25°
