💡 LUMENS vs LUX — What’s the Difference? When designing a lighting system, we often hear the terms Lumens and Lux. But they measure two different things. 🔆 Lumens (lm) → The total amount of visible light produced by a light source. 💡 Lux (lx) → The amount of light falling on a specific surface or working area. 📐 Basic relationship: 1 Lux = 1 Lumen / 1 m² For example, the same 1000-lumen LED can provide: ➡️ 100 lux when the light is distributed over 10 m² ➡️ 50 lux when the light is distributed over 20 m² This is why lux level is more important when evaluating whether a space has sufficient illumination for its intended use. 🏢 In MEP / Lighting Design: 1️⃣ Determine the required lux level 2️⃣ Calculate the required lumens 3️⃣ Select suitable LED fixtures 4️⃣ Determine the number and arrangement of fixtures 5️⃣ Verify the achieved illumination level 📌 Remember: Lumens = How much light the source produces. Lux = How much light reaches the surface. A simple concept, but an impo...
