Real-Time Architectural Lighting Simulation

Choosing the right wattage, beam angle, and fixture placement shouldn’t require waiting days for desktop CAD renders.

I built this lightweight simulator as a fun, interactive playground for beginners and clients to experiment with lighting concepts before diving into heavy DIALux calculations. Drag lights, adjust luminous efficacy, see solid-wall occlusion in action, and get instant lux feedback—complete with one-click PDF reports to guide your final engineering plans.
