Your Project,
Our Engineering
From the initial lighting audit to the complete execution file, our integrated engineering office designs custom LED lighting solutions for horticulture, research and commercial premises.
DIALux/Relux photometric modelling, regulatory compliance, smart controls and CEE/France 2030 financial support: a single point of contact for every project stage.
Our 6-Step Methodology
A rigorous process, from the site audit to the execution dossier, guaranteeing lighting performance, compliance and cost control.
Lighting Audit
Comprehensive survey of existing installations: source types, installed wattages, electrical schematics, wiring condition.
- In-situ PPFD / illuminance measurements
- Uniformity & UGR mapping
- Building characteristics (dimensions, heights, obstacles)

Control Protocols
We select and integrate the appropriate communication protocol for each application, from simple dimming to full IoT orchestration.
DALI-2
BidirectionalInternational standard for dimmable tertiary and horticultural luminaires. Bidirectional communication: control and status feedback for each luminaire.
0-10V
AnalogueSimple luminous intensity control via analogue signal. An economical and reliable solution for installations that do not require individual addressing.
DMX512
High-speedReference protocol for fast lighting scenography. Ideal for zoos, museography and dynamic multi-colour lighting.
Zigbee / LoRa
Radio & IoTWireless communication for group-based luminaire control with status feedback and cloud access. Ideal for large areas and retrofit projects.
Greenhouse Automation
Full integrationNative integration with the leading greenhouse climate management controllers: Priva, Ridder, Hoogendoorn.
Smart Control
Multi-criteriaAdvanced control algorithms combining multiple real-time parameters to optimise production and reduce costs.
- Supplementing natural radiation
- Instantaneous electricity price (spot)
- Daily DLI targets per crop
Cloud & IoT Supervision
Maintain full control of your installation from anywhere. Our cloud platform centralises consumption data, lighting performance and predictive maintenance.
Energy Monitoring
