ARRI Photometrics

What is ARRI Photometrics?

ARRI Photometrics is ARRI’s free mobile app that provides detailed lighting data and photometric charts for their fixtures. Instead of guessing how a light will perform on set, you can use the app to calculate output, beam spread, lux levels, and recommended distances. It’s essentially a digital reference guide for ARRI lights.

How does ARRI Photometrics work?

Users select a fixture (e.g., ARRI SkyPanel, Orbiter, M-Series HMI) and input settings like beam angle, distance, and intensity. The app instantly calculates lux, beam diameter, and field coverage. This helps gaffers and cinematographers plan lighting setups before physically placing lights on set.

Pros

• Free and easy to use.

• Covers all ARRI fixtures with detailed data.

• Calculates output at different distances and beam angles.

• Saves time during pre-production and setup.

• Useful for comparing different ARRI models.

Cons

• Limited to ARRI fixtures only.

• Doesn’t replace hands-on testing for creative looks.

• No direct light control, purely reference-based.

Best Features of ARRI Photometrics

Who is ARRI Photometrics best suited for?

This app is best for cinematographers, gaffers, and lighting designers working with ARRI gear. It’s especially valuable in pre-production when planning how many fixtures are needed and where they should be placed.

ARRI Photometrics Verdict: Is it worth it?

Yes — if you work with ARRI lights, this app is a no-brainer. It won’t control fixtures, but as a planning and calculation tool, it’s incredibly useful and completely free.
