Low Light LED Analyser

Precise color and intensity testing for LED backlit switches and panels

Overview

Automotive manufacturers use LED backlit switches and panels to create a safe, appealing cockpit—nearly invisible by day and clearly legible at night. Because these assemblies often come from different suppliers, maintaining consistent color and brightness is essential.

The Feasa Low Light LED Analyser is purpose-built for these applications, accurately measuring light after it has passed through etched or painted plastic panels where other testers may struggle.

Its high sensitivity delivers fast, repeatable color and intensity measurements across multiple channels, helping manufacturers maintain a consistent appearance across every vehicle interior.
