LIGHTmetric® ONE
spectral LUX Meter

One Instrument. Multiple Applications.

The LIGHTmetric® ONE is a professional full-spectrum light meter for lighting design, color measurement, horticulture and many more applications. As a versatile lux meter with integrated spectral analysis, it measures illuminance, CCT and light quality – with traceable calibration. See the full versatile light meter overview for specifications and application details.

Developed with Filmmakers and Photographers

The LIGHTmetric® ONE spectral lux meter was developed together with filmmakers and photographers – to meet the real demands of the industry. High-quality work requires high-quality equipment when it comes to the spectral measurement of light.

SMART Solution

Compact and handy – easy to use. The LIGHTmetric® ONE is the smart companion on set. Ready for use at any time and always precise.

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.

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 via iOS and Android App

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

All Necessary Measurements and Evaluations

The device covers all essential measured quantities – CCT, lux, spectrum, CRI and more – as well as advanced evaluations such as the SSI (Spectral Similarity Index) and the Lee filter calculation for color temperature (CCT) corrections.

Features Ideal for Architects, Lighting Designers and Installers

The LIGHTmetric® ONE impresses with many functions for architects, lighting designers, installers and technicians. The rotatable measuring head and tripod mount are just as useful as the versatile app control and the SD card slot for storing measurement data.

Human centric lighting evaluations – as required by the WELL Building Standard, for example – are supported by the direct display of the melanopic equivalent daylight illuminance (melanopic EDI).

PAR Measurement of Artificial Plant Lighting

Thanks to its extensive evaluation functions for PAR (photosynthetically active radiation) and other special functions, the LIGHTmetric® ONE is also ideal for evaluating artificial plant lighting and horticultural LED grow lights.
