LETL (Limited Energy Test Lab) is a purpose-built laboratory specializing in testing and validation of PoE and FMP devices, lighting fixtures, automated shades, sensors, and all intelligent building components.
LETL is an independent validation and enablement lab built to help organizations confidently design, deploy, and scale intelligent building systems.
We go beyond testing individual components. LETL focuses on design readiness, interoperability validation, and repeatable delivery practices that reduce risk, accelerate decision-making, and improve outcomes across complex, multi-vendor environments.
Our work ensures solutions are not only technically sound, but ready for real-world deployment and long-term operation.
LETL is a purpose-built testing and validation laboratory for low-voltage and intelligent building technologies. With a core focus on Power-over-Ethernet (PoE), Fault Managed Power (FMP), and Class 2/Class 4 systems, LETL provides rigorous technical evaluation and validation services for manufacturers, OEMs, and system integrators.
Test PoE-integrated LED fixtures for flicker, efficacy, thermal performance, and startup behavior under real-world loads.
Validate PoE and FMP-powered motorized shades for latency, energy use, and motor reliability.
Ensure smart sensors, control devices, and software platforms work seamlessly in dynamic network environments.
LETL provides comprehensive testing and validation services for intelligent building technologies — ensuring performance, safety, and interoperability from the lab to the field.
Test for flicker, efficacy, lumen consistency, and startup reliability under various load conditions.
Evaluate PoE and FMP-powered motors for energy profiling, response latency, and smooth operation.
Validate Class 4 converters, power control behavior, and system response under fault conditions.
Ensure compatibility with BACnet, MQTT, CoAP, REST, and partner ecosystems like Molex and Mecho.
Run devices through thermal cycling, EMI/RFI interference, humidity stress, and real-world network simulation.
Get tailored test scripts and engineering guidance for unique partner platforms and product architectures.
Join an industry-trusted validation network for PoE-integrated lighting. Ensure your fixtures meet the highest standards for performance, reliability, and enterprise integration.
