Lumen Calculator (Lumen to Lux to Candela) — Frequently Asked Questions
Q1 What is 1 Lux? ▾
1 lux is equal to 1 lumen evenly distributed over an area of 1 square meter (1 lx = 1 lm/m²).
Q2 How are candela and lumens related for an omnidirectional bulb? ▾
A sphere encompasses 4π steradians, so Lumens = 4π × Candela ≈ 12.57 × cd.
