Safety and certification

What we test

  • Electrical safety: protection against electric shock, insulation, and leakage current
  • Mechanical and thermal safety: resistance to heat, fire, and mechanical stress
  • Construction review: markings, documentation, and component compliance

Your benefit

  • Recognized certification marks (VDE, ENEC, GS) trusted worldwide
  • Reduced retesting through harmonized test programs
  • Confidence and credibility in tenders and customer relations


Performance and Quality Verification

Validate the real performance of your luminaires — from light output and color quality to endurance and flicker. 

True quality goes beyond compliance — it’s proven by performance. VDE provides independent verification of photometric, electrical, and thermal characteristics to show how your luminaires perform in real-world conditions. Our test results help manufacturers, planners, and end-users make informed, data-driven decisions.

Performance and quality verification

What we measure

  • Luminous flux and efficacy: light output and efficiency under defined conditions
  • Light distribution: uniformity, beam pattern, and optical design validation
  • Color quality and stability: CCT, CRI, TM-30, color shift over time
  • Flicker and stroboscopic effects: compliance with IEC TR 61547-1
  • Thermal and endurance performance: luminous maintenance (LxBy), driver lifetime, and thermal behavior

Your benefit

  • ENEC+ or VDE Quality Tested mark as visible proof of verified performance
  • Credible, comparable test data for datasheets, marketing, and public tenders
  • Confidence in declared performance values and warranty statements
  • Support for eco-design and sustainability declarations (energy efficiency, photobiological safety, etc.)


Human and Environmental Lighting

Demonstrate that your lighting supports well-being, protects the night sky, or optimizes plant growth. VDE provides tailored testing for human-centric, sustainable, and horticultural lighting systems.

Light affects not only visibility but also health, ecosystems, and sustainability performance. VDE’s Human and Environmental Lighting services combine spectral, biological, and environmental expertise to help manufacturers design and prove responsible lighting solutions.

Human and Environmental Lighting

What we evaluate

  • Human Centric Lighting (HCL): VDE tests HCL systems for their ability to support human well-being and circadian rhythm across different environments. Measurements include illuminance, color temperature range, color rendering, glare, flicker, and melanopic ratio, as well as the accuracy and dynamics of light changes — verified according to CIE S 026 and DIN SPEC 5031-100.
  • Dark Sky Compliance: assessment of upward light output ratio (ULR), correlated color temperature (CCT), and glare control to minimize light pollution. Dark-sky principles aim to preserve natural night environments by reducing excessive or misdirected artificial light. Limiting light pollution protects ecosystems, human circadian rhythms, and the visibility of the night sky.
  • Horticulture Lighting: safety and performance certification for plant lighting or vertical gardening, including measurement of photosynthetic photon flux (PPF) and photosynthetic photon efficacy (PPE) for horticultural luminaires
  • Sustainability & Life Cycle: evaluation of LCA indicators, repairability, recyclability, and environmental impact over the product life cycle

Your benefit

  • Documentation supporting ESG and Green Deal objectives
  • Quantifiable proof of light quality beyond energy efficiency
  • Differentiation in public tenders and sustainable product labels
  • Credibility through independent, science-based evaluation by VDE


Smart, Connected and Cybersecure

Smart luminaires must be interoperable and secure. VDE tests your connected lighting for interface compatibility, communication reliability, and cybersecurity.

The future of lighting is digital, connected, and data-driven — but also increasingly exposed to cyber risks. VDE helps manufacturers ensure that intelligent lighting systems remain safe, interoperable, and compliant throughout their lifecycle.

Smart, connected and cybersecure

What we evaluate

  • Interoperability & Interfaces: testing of control interfaces such as DALI, D4i, and Zhaga Book 18, ensuring plug-and-play compatibility and open communication across systems
  • Communication Reliability: verification of wireless and wired protocols (e.g., Bluetooth Mesh, Zigbee, Wi-Fi) for robust data exchange and minimal latency
  • Cybersecurity Assessment: evaluation according to EU RED Articles 3.3 (d–f), covering authentication, encryption, and secure update mechanisms
  • Software Validation: testing of embedded firmware and control applications to identify vulnerabilities, validate code integrity, and prevent unauthorized access
