As smart-building technologies continue to evolve, the need for trusted, vendor-neutral validation has become essential. LETL was created to answer this need by providing a transparent, independent, and reliable validation process for PoE, DC, FMP, and other smart-building systems.
At LETL, our mission is simple:
Enable manufacturers, integrators, and ecosystem partners to demonstrate the true performance, safety, and interoperability of their solutions.
Why LETL Was Created
The smart-building industry is expanding quickly, with new devices, new communication standards, and integrated ecosystems. However, many organizations struggle to prove:
- That their devices work together in a real environment
- That their systems follow global standards
- That their solutions are safe, reliable, and scalable
- That interoperability is guaranteed across vendors
LETL provides a trusted and independent environment where all these aspects can be validated with complete neutrality.
What Makes LETL Different?
Unlike traditional certification bodies, LETL is fully independent.
We do not develop hardware or software — ensuring a neutral and unbiased validation methodology.
Our approach focuses on real-world testing, not only theoretical compliance.
Manufacturers and system partners can rely on our process to confidently demonstrate the reliability and compatibility of their solutions.
LETL Validation Workflow
1. Device & System Onboarding
We begin by analyzing the device or system architecture, communication methods, power requirements (PoE/DC), and intended use.
This creates a clear understanding of real-world expectations.
2. Ecosystem Validation (Independent System Testing)
Solutions are tested in an isolated environment that accurately simulates production conditions.
This ensures:
- Interoperability
- Performance reliability
- Safety compliance
- Benchmarking against LETL standards
The result is a transparent evaluation that manufacturers can use to improve their products or demonstrate compatibility with ecosystem partners.
3. LETL Validated Certification
Devices or systems that successfully complete the workflow receive the LETL Validated designation — a mark that proves:
- Independent assessment
- Transparent results
- Vendor-neutral evaluation
- Trustworthy performance
This certification provides strong value to partners, customers, and industry stakeholders.
