GL SPECTROLUX
Robust design. Exceptional performance. Budget-friendly.
Handheld spectral light meter
LED and other lighting technologies require fast, accurate measurements that many light meters simply can’t achieve. As a leader in professional light measurement test devices, we designed the GL SPECTROLUX as easy-to-use, affordable spectrometer for every lighting professional.
Based on our popular GL 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.
Easy lighting audits
Use this spectral device for on-site measurement of the existing or new lighting installations and prove the compliance of the installation with designs’ specific requirements.
Quality lighting products
Get control of your lighting products and components quality. Use this device to check components like LEDs, drivers or lenses when you buy. Why not using this device as a sales tool to show the advantages of your products when you present them to clients or end-users?
Simple evaluation and adjustment
If you are setting stage lighting for an accurate CCT/CRI of museum and studio lights to proper lux levels, this device makes it easy to analyze and adjust lighting parameters. There is a useful uniformity testing option available on board the handheld meter for convenience.

GL SPECTROLUX Usage
This handheld affordable spectrometer 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.
Results at the touch of a button
Modern electronics and efficient design yield highly accurate results in seconds… every time. All important metrics are displayed instantly on the LED display, allowing you to make better assessments, faster.
Affordable spectrometer - low price, high performance
Even though this is GL’s most budget instrument, it has industry best DIN Class B cosine corrected measurement head as a standard accessory allowing for optimal measurement of light from the 180° measurement condition, according to Lambert’s Cosine Law.
Built to last
Despite its attractive price, GL SPECTROLUX illuminance light meter does not sacrifice quality of materials. Designed and manufactured in Europe, these solidly constructed devices are in a class of their own and ready for the rigors of field audits.

* 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 25°C, relative humidity 45%.
