Lumen Lab

Lumen Lab is a web-based lighting design and calculation workspace built for fast, practical decision-making. It delivers clear, real-world results through a streamlined workflow that supports both quick lumen-method estimates and optional IES-driven refinement.

What Lumen Lab Provides

Lighting calculations for interior and exterior applications
Interactive 3D visualization of rooms and sites with fixture or pole placement
Optional IES photometric input for enhanced accuracy and optics modeling
Shareable reports and PDF exports for project review and handoff
Project saving and reloading for authenticated users

Runs entirely in-browser with no plugins or installation.
