What Relux does
RELUX Informatik AG (Relux) is a Swiss-headquartered software company that develops professional lighting planning and sensor simulation tools for the lighting, architecture, and electrical engineering industries. Founded in 1998 and based in the Basel region of Switzerland, Relux serves three primary user constituencies: professional lighting designers and engineers who plan indoor installations, outdoor and street lighting planners, and luminaire and sensor manufacturers who want their products exposed to the global planning community. The company operates in 25 languages and counts enterprises such as Sonepar, Atkins, and Trilux among named users.
The core technology stack centers on ReluxDesktop, a free desktop application that combines photometric calculation, photorealistic rendering via Enscape, BIM/CAD interoperability (bidirectional interface to Autodesk Revit, plus AutoCAD and TinLine Plan), and standards-compliant calculations across EN, ISO, CIE, and DIN frameworks. The product is differentiated by its integrated sensor planning capability under the sensNORM/IEC 63180 standard, developed in partnership with METAS (the Swiss Federal Institute of Metrology), and increasingly by AI features including 2D-to-3D floor plan digitization and AI-generated interior visualizations. ReluxNet, an online luminaire and sensor database with over 1,000 free 3D objects, functions as the network backbone, with a new 2026 integration to pCon.catalog materially expanding the available 3D content library.
Relux monetizes through a freemium, two-sided marketplace model. End-user planners download ReluxDesktop at no cost and use it free when planning with member-manufacturer products. Revenue is generated primarily from manufacturer membership fees (paid by luminaire/sensor producers to be featured in ReluxNet), paid add-on licenses such as ReluxThirdParty (CHF 67/year) that unlock calculation with non-member products, OEM calculation web services (StreetCalc, WebService, SceneCalc, SensCalc, EmergencyCalc, OnCalc) embedded in manufacturer platforms, and self-paced and instructor-led training courses. Distribution is global, self-serve, and product-led, with complementary marketing through webinars, tutorials, and an AI-powered chatbot (Luxi) launched in 2025.

Revenue model
- Software Licensing (Add-ons): ReluxDesktop core software is free for planning with member products. Revenue generated from paid add-ons like ReluxThirdParty license (CHF 67/year for single license) enabling calculation with non-member products. Also add-ons for ReluxCAD (Revit, AutoCAD), ReluxTunnel, ReluxSport, ReluxObtrusiveLight, ReluxEnergyCH, Metaroom.
- Manufacturer Membership: Luminaire manufacturers pay for membership to have their products listed in the ReluxNet database, making them available for free use by planners worldwide. This creates network effects.
- Self-Study Training Courses: Online self-paced training courses for ReluxDesktop including Beginner (1.00 CHF), Interior, Street&Place (96.65 CHF for 90 days access), and Access courses in multiple languages.
- Live Learning/Training: Instructor-led live courses and webinars (FUN with RELUX) for professional development and software training.
- OEM Services: Custom OEM solutions for manufacturers including StreetCalc, WebService (indoor-calc), SceneCalc, SensCalc, EmergencyCalc, OnCalc web services.

Relux competitors and assessment
Company assessmentOthers
- Signify (Philips Lighting): Global lighting OEM whose products populate ReluxNet; Signify also operates its own lighting design tools (e.g., Interact/LightPlanner) and is both a major potential ReluxNet member and an adjacent ecosystem participant.
- Zumtobel Group: European lighting manufacturer and ecosystem participant whose luminaires are listed in ReluxNet; also develops proprietary lighting design and configuration tools that touch the same planner workflow.
- ERCO: Architectural lighting manufacturer listed among Relux members; ERCO also provides its own specification and planning software that competes for the same lighting designer attention.
- Acuity Brands: North American lighting manufacturer with its own agent-facing design and configuration tools; a potential ReluxNet member and adjacent ecosystem participant for the same lighting designer buyer.
- EasternGraphics (pCon): Provider of pCon.planner and pCon.catalog — ReluxDesktop 2026 now integrates pCon's 3D and material library; they serve overlapping interior planning/design personas and could expand into lighting calculation.
Broad incumbents
- Trimble: Broad design/CAD and construction software incumbent (SketchUp, Tekla); a potential alternative environment for lighting planning and a vendor whose roadmap choices could influence Relux's CAD/BIM integration surface.
- Autodesk: Autodesk Revit and AutoCAD are the BIM/CAD platforms that ReluxDesktop integrates with; Autodesk is also a broad incumbent with potential capability to bundle native lighting calculation features that overlap with Relux.
- Bentley Systems: Infrastructure-focused BIM/digital-twin platform (OpenBuildings, OpenRoads) that competes in the broader building design software space where Relux's BIM add-on positioning overlaps.
Direct peers
- DIAL GmbH (DIALux): DIALux is the closest direct competitor to ReluxDesktop — free professional lighting planning software with luminaire database and BIM integration, serving the same lighting designer/engineer persona in Europe and globally.
- Lighting Analysts (AGi32): AGi32 is a long-standing lighting calculation and visualization software used by professional lighting designers, directly competing with ReluxDesktop for indoor and outdoor lighting planning workflows.
