Full photometric calculation online
Check a luminaire, get an illuminance map to code and build a project for a whole apartment — free.
A full calculation in three steps
No tables or reference books — the tool takes the norms and coefficients on itself.
STEP 01
Build the space
Set the room or lay out a whole apartment in the 3D scene — walls, work plane and furniture.
STEP 02
Add the luminaire
Upload an IES file to check the real fixture, or set flux and beam angle manually.
STEP 03
Get the result
An illuminance map on the work plane, the exact number of fixtures and a check against the norms.
Features
Engineering-grade calculation with the simplicity of a calculator
Full illuminance map
E avg, E min, E max and U₀ on the work plane — not just an average number.
Luminaire check by IES
Upload the manufacturer’s IES file and calculate on the real photometry of the fixture.
Whole-apartment project
Several rooms, furniture and a 3D scene in one lighting project — save and share.
The right count, no mistakes
The exact number of fixtures to hit the norm — with safety and non-uniformity factors built in.
To the norms
15+ room presets with recommended illuminance from current standards.
