Robust Design. Exceptional Performance. Budget-friendly.
LED and other lighting technologies require fast, accurate measurements that many light meters simply can’t achieve. As a leader in light measurement test devices, we designed the Spectrolux to put affordable, easy-to-use, professional light measurement instrumentation in hands of every lighting professional.
Based on our popular Spectis 1.0 Touch, this simplified model is ideal for immediate measurement of illumination level & homogeneity, Color Temperature and coordinates, Spectral Power Distribution, LED color rendering, PAR/ PPFD and more. Each device is individually calibrated and traceable to international reference standards and equipped with a laboratory grade measurement head for superior accuracy and repeatability that sets new price and performance standards for the industry.
At GL, we focus on developing professional instruments for light measurement in wide ranging applications that break the normal technical boundaries. Our portable light meters are built for everyday users, and not just for high end laboratories, R&D or incoming quality control. As the LED lighting market becomes more competitive and more professional installations and solutions are provided to the market, the need for reliable on-site measurements is increasing. Our compact devices have many practical applications, offering lighting professionals a simplified, yet dependable, spectral light meter.
This handheld spectral lux meter can be used to evaluate lighting installations, quick control of LED lamps and luminaires or even to support application and sales engineers to quantitatively highlight the advantages of modern lighting systems to customers. Finally, it can also be used for competitive insights by evaluating competitors’ products and installations.

* Dynamic range is spectrum related and should be calculated separately for any light source. Estimated dynamic range for typical 4000 K white LED.
Range estimated for optical system made to default specification. Alterations of that are often possible. Please consult technical support if you are looking for specific parameters.
** Absolute measurement uncertainty immediately after calibration. The expanded uncertainty corresponds to a coverage probability of 95% and the coverage factor k = 2.
Parameters valid in laboratory conditions 25deg C, relative humidity 45%.
