GL SPECTROLUX

GL SPECTROLUX

Robust Design. Exceptional Performance. Budget-friendly.

The GL Spectrolux handheld spectral lux meter sets new price standards. Based on our popular Spectis 1.0 Touch, it evaluates light quantities such as lux, CRI, CCT, color and more in a compact handheld package. The GL Spectrolux includes a laboratory Class B measurement head for superior accuracy and repeatability. Each device is individually calibrated and traceable to international reference standards.
