Lighting Technicians
Calculate inverse square falloff, beam spread, and cosine correction instantly — no spreadsheet needed.
Every Data Point. One Pocket.
Light Database
Every Light. Every Brand. One Place.
An extensive catalog of professional fixtures from ARRI, Aputure, Kino Flo, and more — with real specs including power draw, weight, dimensions, and lamp type. No internet required on set.
Photometrics
Know Exactly What Your Light Will Do.
Real photometric data from manufacturer testing, visualised as interactive charts. Footcandle output vs. distance for every configuration — spot, flood, fresnel, bare bulb. Switch setups in seconds.
Calculator
Calculate. Adjust. Never Guess.
Go beyond inverse square law. Account for light height, target height, and horizontal offset with Cosine Law correction. Or run the reverse: give it your target footcandles and it'll tell you the distance.
Built for Real Sets. Real Problems.
Pre-Production Planning
Input your target exposure — say T4 at 800 ISO — and know immediately if your 300d will make it from 20 feet away, or if you need to upgrade to an 1200d.
On-Set Adjustments
The director wants to push the key light back 5 feet. Dial in the new dimmer setting instantly to hold your stop — without pulling anyone out of the moment.
Fixture Comparisons
ARRI M18 vs. Aputure 1200d? Side-by-side photometric data cuts through spec-sheet noise and tells you which unit is the smarter choice for the scene.
Your next shot deserves
the right light.
