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 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.

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.

Spectrolux Usage

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.

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.

Low Price, High Performance

The industry best DIN Class B cosine corrected measurement head is 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, the 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.
