Colasse, innovator in LED lighting solutions since 2006
Colasse is a Belgian company founded in 2006. It designs and manufactures LED lighting fixtures – its Vegeled EOS LED rails are made in Seraing – and delivers complete lighting and energy projects, from study to commissioning. Much more than an equipment manufacturer, Colasse demonstrates great flexibility and supplies profitable, innovative and custom solutions, meeting the operational needs of its customers and environmental constraints. 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. The team includes engineers with complementary experience in industry and agronomy.

From design to commissioning, and well beyond: a single point of contact coordinates your lighting project.
Design and engineering
We analyse your uses, constraints and objectives, then carry out lighting calculations, simulations and plans. As an independent company, we choose the technologies best suited to each project.
Custom manufacturing
Our Vegeled EOS LED bars are made in our workshops in Seraing. We also design custom luminaires, kits and control systems, including prototypes.
Installation and commissioning
Our teams install and commission your lighting, including on occupied sites and with full discretion, in compliance with safety rules (VCA).
Long-term support
Our job doesn't end at commissioning: we monitor the performance of your installations and stay at your side to preserve their efficiency.
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.
