LIT Systems Duo 1

LIT DUO 1 reinvents a light meter by combining all essential tools—color, exposure, illuminance, spectrum, and flicker meter - into one pocket-sized device inside a durable aluminum body.

Designed for ease-of-use and fast workflow, LIT DUO 1 also introduces an entirely new user interface based on pioneering software and tactile physical controls.

FEATURES

• Accurate and consistent colors for any type or brand of light sources.
• Set correct exposure for any camera – Adjust all parameters, set any value you want. Apply ND filter or exposure compensation.
• Match "Color Temperature" lights – Measure two lights and see the correction filters.
• Measure Illuminance – In either lux of foot-candles.
• Measure Spectrum – Evaluate quality of your lights.
• Measure Flickering– See which shutter speeds to avoid. Up to 7kHz.

WHAT'S IN THE BOX

• LIT DUO 1
• Neck strap, NNylon, 1m length
• Hard protective case, ‍EVA foam composite, 3 layers. Built-in pocket for spare batteries.
