Lighting Calculator for Sets
Free · In‑App Purchases
LightStop is a professional lighting calculator built for cinematographers, gaffers, electricians and film students.
Calculate required illuminance from camera settings, check verified fixture photometrics, apply gels and diffusion, compare fixtures side by side, build your lighting truck and estimate power loads for EU and US sets.
Designed for real film work, LightStop helps you understand exposure, output, distance, modifiers and power in one clean, practical tool.
FEATURES
• Lux / foot-candle exposure calculator
Calculate required light levels from ISO, frame rate, shutter angle, T-stop, ND and camera filters.
• Verified fixture catalog
Browse real fixture photometric data from manufacturer sources and technical documentation.
• Fixture detail calculator
Adjust distance, output mode, CCT, gels and diffusion to estimate lux, foot-candles, exposure and beam size.
• Estimated CCT with gels
Apply CTO / CTB filters and see the estimated resulting color temperature using mired shift calculations when data is available.
• Compare fixtures
Compare 2–4 fixtures at the same distance and modifiers, including output, T-stop, watts, beam diameter and stop difference.
• My Truck
Create lighting packages, add fixtures, set quantities, favorites and nicknames.
• Power View
Estimate total load, current, phases and fixture distribution for EU and US power systems, including 230V, 120V, split-phase and three-phase setups.
• Metric and imperial workflow
Switch between meters / feet and lux / foot-candles.
LightStop is made for set planning, pre-production, teaching and fast technical checks on location.
NOTES
Photometric values may vary depending on fixture condition, lamp age, voltage, optics, modifiers, firmware, beam angle, accessories, calibration and manufacturer measurement conditions.
Power View is an estimation tool for planning only. Always confirm electrical loads, distribution and safety with a qualified electrician or gaffer according to local regulations.
