Our Mission
The platform light deserves.
Open tools.
A platform that makes every lighting project easier. This is OpenLumen.
The industry ran on expensive desktop software, proprietary formats, and fragmented workflows for too long. Designers juggled tools. Contractors guessed at layouts. Manufacturers buried IES files behind clicks. Everyone lost time.
We built OpenLumen to change that. One browser-based platform that brings layout design, photometric analysis, IES file management, and professional reporting into a single workspace.
Then we went further. We made it open. A community-driven luminaires library where the data belongs to everyone. A free tier with full access to design tools. Features that let professionals share, discuss, and learn together.
This is not just a tool. It is a better way to work with light.
Our Values
Tools should be open
Photometric tools belong to the profession, not behind walls. Our community library is free to search, download, and contribute to. Verified through consensus, not gatekeeping.
The community builds the platform
Why Open Matters
For decades, lighting software followed the same model: expensive licenses, heavy installations, proprietary ecosystems.
OpenLumen takes a different path.
Free at the core
The tools that matter most are free forever.
Use IES files from any manufacturer in one workspace.
No downloads, no installations, no IT department.
Community-verified
Data gains trust through multiple contributors
Transparent
Open data, open community
We spent years chasing IES files, rebuilding layouts in desktop software, and explaining photometric data to customers who just wanted to know if the light would be bright enough.
So we built the tool we always wished existed.
