Free lighting‑design web calculator for LED track lights and downlights. Input mounting distance or beam diameter to instantly get beam angle, spot size, plus visual beam‑cone preview. Switch between metric / imperial units. It includes standard beam‑angle reference tables for retail, artwork accent, wall‑washing and ambient lighting projects.
Hey Product Hunt community 👋 Today we’re launching our free LED Beam Angle Calculator.
We built this browser‑based tool for lighting designers and retail specifiers to quickly work out beam angle, spot diameter and beam spread without heavy optical software. Just plug in mounting height or beam size and get instant results with visual beam‑cone preview. Metric and imperial units supported, plus reference tables for common lighting‑design scenarios.
We’d love your feedback! What other lighting calculators would you find useful? Drop your thoughts and feature requests below. Happy to iterate based on real‑world design needs 🚀
