Tesis, which has long been an integral part of the ERCO programme, has reached a new level of performance following intensive further development. Its lighting technology convinces with maximum brilliance and efficiency. The robust, corrosion-free polymer housing ensures durability and easy handling. Whether directional spotlights with interchangeable lenses and zoom light distributions, uplights or wallwashers – Tesis sets the benchmark in outdoor lighting.
Benefit from greater planning reliability. Our directional spotlights with interchangeable lenses allow you to change the light distribution on site. This means you can react to unforeseen events at any time.
Tesis wallwashers offer outstanding uniformity, from the floor to the entire wall.
What if the beam angle cannot be defined exactly during planning? Adjustable zoom lenses provide the solution.
Adjustable light heads, precise wallwashers and anti-glare elements ensure light reaches only where needed.
Tesis was developed and manufactured for real-world demands.

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.

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

Zoom spot
Zoom directional luminaires feature a continuously adjustable beam angle. With the spot to wide flood zoom range, smaller objects can be accentuated effectively at an inclination angle (α) of about 30°. Oval zoom is suitable for linear-shaped objects to model the object without distorting the effect as a result of excessive shadowing. This set-up also prevents shadows cast by the observer.

Wallwash
Tesis wallwashers offer exceptional uniformity on vertical surfaces. Lens wallwashers are the right choice for flush mounting in the floor. Semi-recessed wallwashers allow installation particularly close to the wall.
The distance of Tesis lens wallwashers to the wall (a) should be about one third of the room height (h).
Arrangement for recessed wallwashers: a = 1/3 x h
For good linear uniformity, the distance (d) between Tesis lens wallwashers can be up to 1.3 times the distance to the wall (a).
Arrangement for recessed wallwashers: d ≤ 1.3 x a

Wallwash
For semi-recessed wallwashers, a minimum wall distance (a) of around 1/6 of the room height is sufficient.
Arrangement for semi-recessed wallwashers: a = 1/6 x h
For good longitudinal uniformity, the distance (d) between semi-recessed wallwashers may be up to 6 times the distance to the wall (a).
Arrangement for semi-recessed wallwashers: d ≤ 6 x a

Tesis directional spotlights not only allow you to align the light head but also to change the light distribution. The luminaire is designed so that the cover glass can be removed on site without voiding the warranty. The lens can be replaced tool-free, for example, changing from a narrow spot to a wide distribution or even a zoom light distribution.
If your requirements change, simply change the light. Achieve even better glare control with honeycomb louvres. Filters that can be easily attached influence the light spectrum. Special lenses modify the shape of the light beam.
Do you prioritise elegant, flush installation without compromising uniformity or performance? If so, Tesis recessed wallwashers are the right choice. The ideal solution for buildings adjacent to traffic-calmed zones and plazas. The luminaires are mounted slightly further away from the wall and can be driven over using appropriate installation housings.
To address all planning challenges, ERCO offers semi-recessed wallwashers that can be mounted extremely close to the wall with only *1/6 of the wall height. They feature gentle, uniform light beams that start at the ground and extend to great heights.
ERCO semi-recessed wallwashers feature highly efficient lighting technology that allows for above-average luminaire spacing of up to six times the wall distance. Saving both investment and maintenance costs.
Would you like semi-recessed luminaires in a special colour? With our 'ERCO Individual' service, all RAL colours are available. Simply contact us.
The zoom lens allows for an infinitely variable beam angle. This ensures precise illumination even when luminaire positions deviate. Rotationally symmetric light distribution is available, ranging from spot to wide flood (15° - 65°). An oval zoom variant (approx. 20° x 70° – 75° x 60°) allows for fine adjustment of oval light beams. This allows different lighting tasks to be fulfilled with just one luminaire, ensuring the light always hits its target area.
Moisture, heavy rain or snow are no problem. IP68 protection rating confirms the luminaires withstand permanent immersion in water.
Corrosion-resistant, high-quality plastic housings enable direct installation in the ground.
The choice is yours. For particularly minimalist designs, ERCO offers luminaires with flush mounting details.
With special recessed housings, most Tesis ground-recessed luminaires are designed to be driven over by vehicles with pneumatic tyres
