Colasse forms a real partnership with its customers and offers them complete solutions as their needs and technology evolve.
Colasse is active in horticulture and the biological applications of light under the brand name Vegeled™. The company is also present in the lighting industry (e.g. harbour cranes, hospitals, hotels, etc.) and in the specialised retail business with its Spotled™ brand. Established in the greater Liège region, the company has more than 850 customers worldwide, mainly major companies and government research centres.

What we do
We ANALYSE
Our work always starts with the customer's requirements. By listening to, understanding and analysing this information, we write a proper functional design specification, which is the basis of our journey towards your solution.
We SOLVE
To find the solution, we activate our internal and external resources. We make calculations and drawings, and sometimes build prototypes, to check that the solution complies with the customer's requirements.
We DELIVER
Once the concept or the prototype is approved, we produce your lighting product, whether it is a special LED chip, an LED kit or a complete lighting fixture.
Energy performance
Energy challenges go far beyond lighting. To improve the long-term efficiency of a building or facility, it is now essential to understand, measure and manage its energy consumption as a whole. This is why Colasse has expanded its expertise into energy performance.
Energy audits, monitoring & management
We help you understand the real energy costs of your installations, track consumption, identify inefficiencies and make better-informed decisions, using the monitoring solutions developed by our partner Ewattch™.
The data gives you the insight you need to optimise usage, measure results, prioritise investments and achieve lasting savings.
Electrical engineering solutions
From electrical distribution boards to EV charging stations, batteries, photovoltaic systems and control solutions, we help you integrate the most relevant equipment to reduce your carbon footprint and move towards a more autonomous, efficient and responsible approach to energy management.
