LETL (Limited Energy Test Lab) is a purpose-built testing and validation laboratory for low-voltage and intelligent building technologies. We specialize in Power-over-Ethernet (PoE), Fault Managed Power (FMP), and Class 2/Class 4 systems — delivering high-integrity technical evaluation and validation services for manufacturers, OEMs, and system integrators.
Our purpose is to accelerate the adoption of intelligent building technologies by setting a high bar for quality, safety, and interoperability through specialized testing and validation.
To accelerate the adoption of intelligent building technologies by setting a high bar for quality, safety, and interoperability through specialized testing and validation.
To lead the future of intelligent building validation through rigorous testing, deep expertise, and a commitment to innovation and trust.
LETL validation helps manufacturers win projects faster with trusted, verified performance.
Meet the stringent requirements of top-tier clients like Cisco, Schneider, and other global enterprises.
Validate devices under real-world scenarios to avoid costly deployment failures.
Ensure compatibility across ecosystems including Molex, MHT, Mecho, and more.
LETL was created to address a critical gap in the intelligent buildings ecosystem: the lack of independent validation paired with practical delivery guidance.
Modern buildings rely on tightly integrated systems spanning power, networking, controls, software, and operations. Failures often occur not within individual products, but at the intersections between them. LETL exists to validate those intersections and help teams design with confidence.
In addition to lab-based validation, LETL supports organizations with structured frameworks, documentation, and enablement that turn complex designs into repeatable, scalable solutions.
LETL supports partners, integrators, and solution providers in building a consistent and scalable delivery practice for intelligent buildings.
This includes:
The objective is to reduce guesswork, minimize late-stage changes, and enable predictable execution across projects.
LETL provides training and enablement services designed to support teams before, during, and after deployment.
Training focuses on:
Enablement can be delivered as workshops, design sessions, or project-specific engagements based on need.
LETL engagements are structured to support both early design phases and post-deployment validation.
Pre-deployment services focus on design clarity, integration readiness, and risk reduction.
Post-deployment services focus on confirming systems perform as intended and align with agreed scope and operational expectations.
Each engagement is scoped based on project complexity, number of systems involved, and depth of validation required.
Engage LETL to validate solutions, strengthen delivery practices, and reduce risk across intelligent building projects.
