Illuminance Standards for Indoor Spaces

Adequate lighting prevents eye strain. Standards recommend different Lux levels: bedrooms require lower ambient light (100 Lux), kitchens require task lighting (250 Lux), while office desks and drawing boards require high intensity (500 Lux).

Frequently Asked Questions

What is the difference between Lux and Lumens?
Lumen (lm) measures the total light output emitted by a bulb. Lux (lx) measures the intensity of light falling on a surface area (1 Lux = 1 Lumen per square meter).
