any time and always precise.

Best Purpose

BEST Purpose

Users from the film and television
industry were actively involved in the
development of the device.
This ensures that the device is optimally
adapted to the particular needs of individual users.

Low Cost

High QUALITY, attractive DESIGN and
COST-EFFICIENT

The attractive price
of the measuring device
belies the high-quality design
of the light measurement technology.

Connectivity

Compact, handy and intuitive to use! The LIGHTmetric® ONE is the smart companion on set. Using the iOS and Android app (Bluetooth), remote control and data handling is child's play.

Sophisticated design at an attractive price

When developing the LIGHTmetric® ONE, the focus was on functionality, perfection and an attractive price. We also pass these attributes on to our customers. Our ISO 17025 traceable calibrations testify to our striving to always offer you the best possible measurement technology.

All necessary measurements and evaluations

The device has all the necessary measurement variables (CCT, Lux, spectrum, CRI, ...) as well as other evaluations such as SSI (Spectral Similarity Index), Lee filter calculation for color shifts (CCT), etc.

Features ideal for architects, lighting designers and installers

The LIGHTmetric One also impresses with many functions ideal for architects, lighting designers and technicians, and many more. The features such as the rotatable measuring head and tripod mount are just as advantageous as the versatile control via app. Human centric lighting evaluations, as required by the WELL Building standard for example, are supported by the direct display of melanopic equivalent daylight illuminance.

Measurement of artificial plant lighting

Thanks to its extensive evaluation functions for PAR and other special functions, the LIGHTmetric® One is also ideal for evaluating artificial plant lighting.
