LIT DUO 1 is a modern all-in-one light meter for filmmakers, photographers, video creators, lighting designers, and other professionals who need fast, reliable, and intuitive control of light. It combines the essential tools for exposure, flash, colour temperature, spectrum, illuminance, and flicker measurement in one compact handheld device.
LIT DUO 1 is designed to replace slower, more fragmented metering workflows with one compact and easy-to-use device. It brings together the core tools modern creators need for exposure, flash, colour, illuminance, spectrum, and flicker analysis, while keeping operation fast, practical, and easy to learn.
Built for real-world production use, LIT DUO 1 combines tactile controls, a compact form factor, durable construction, modern connectivity, and an actively evolving software.
It is made for users who want professional capability without complicated operation.
Who Is It For?
LIT DUO 1 is designed, built, and optimised for:
LIT DUO 1 is designed around the needs of modern creators who work across film, video, photography, and lighting. Instead of forcing users to carry separate meters or work through slow and complicated interfaces, it brings the key measuring functions together in one compact device built for speed, clarity, and everyday use.
It is also designed as a platform that continues to improve through firmware updates, giving users more flexibility and value over time.
