Overview
The Feasa LED Life Tester enables accelerated life testing and continuous monitoring of LEDs through extreme temperatures from −65°C to +125°C. Where conventional LED test instruments cannot operate inside environmental chambers, the Feasa LED Life Tester delivers reliable LED data throughout the entire test cycle.
Understanding how LEDs perform over thousands of hours is important for predicting long-term reliability. The LED Life Tester continuously records color and intensity as devices are exposed to extreme temperatures, providing valuable insight into performance and degradation over time.
With the analyser module positioned outside the environmental chamber, it delivers fully automated long-term testing while continuously recording LED performance throughout the entire test cycle.
Built for the long run. Trusted globally.
