Recognised French expertise since 1977
For more than 45 years, LEC has been designing and manufacturing custom LED lighting solutions in France. Thanks to full control of the process—from design to production—we ensure durable, high-performance luminaires tailored to the demands of urban and architectural environments.
By your side, from design to installation
Every project is a human and technical journey. Our teams are involved at every stage, from the initial idea to the final lighting installation, to ensure results that meet expectations. We are committed to co-creating solutions with specifiers, architects, and installers, adapting to each context while combining technical expertise with artistic vision.
Our engineers and technicians do more than design products: they go on site, analyse specific constraints, and carry out in situ tests to ensure that each luminaire integrates harmoniously into its environment. Prototypes, real-world testing, optical adjustments, simulations—every step is taken to guarantee a unique visual experience.
This approach is perfectly summed up by lighting artist Yann Kersalé on the MuCEM project in Marseille:
“I insisted on working with LEC again because I knew we would move together toward the transformation of the object.”
Rigorous in-house testing
Each luminaire undergoes a series of tests to ensure its strength and durability. Our IP (Ingress Protection) tests assess resistance to dust and water, ensuring perfect suitability for the most demanding outdoor environments. In parallel, IK (Impact Resistance) tests measure robustness against mechanical impacts.
90% of our luminaires are IK10 certified, the highest level of protection, guaranteeing optimal resistance to impact and vandalism.
Thanks to these rigorous in-house controls, we provide our clients with lighting solutions that are reliable, durable, and perfectly suited to the constraints of urban environments.
Enhanced protection against water ingress
We place paramount importance on the watertightness of our luminaires. Beyond the design of perfectly sealed housings and gaskets, we have developed an innovative proprietary process to prevent water from rising through the power supply cables.
This unique break system guarantees:
- Perfect sealing within the luminaire
- Extended lifespan of the installations
- Optimal installation in recessed or outdoor applications
LEC has implemented a unique process designed to eliminate the “pumping effect” within the cable, which is responsible for moisture rising into luminaires. While the NF C 17-200 standard only requires sealing of the cable sheath, LEC has gone further by first developing a break system that blocks gaseous or liquid flow between the sheath and the conductors, as well as between the strands of flexible multi-core wires.
Today, this solution has evolved into an innovative membrane that naturally balances air pressure within the luminaire, ensuring greater stability and permanently eliminating the pumping effect.
This internal blocking system guarantees optimal protection against ingress, even under installation conditions where watertightness could otherwise be compromised.
Realistic simulations for a fully controlled project
Our teams create precise simulations to visualise the final outcome before installation. By modelling the lighting under real-life conditions, we optimise each project to ensure impeccable aesthetic and technical results. If a simulation proves too complex, we carry out on-site visits to refine it and ensure perfect adaptation to site-specific constraints.
