Professional Lighting Industry Statistics

Lighting is still responsible for about 40% of building electricity use, but the right efficiency and daylight controls can cut that demand dramatically while LED and smart lighting markets are accelerating fast with the global LED market rising from $72.2 billion in 2022 toward $143.8 billion by 2030. This page also connects the practical design outcomes to the standards and test methods that govern real performance and safety so you can see where energy savings, color quality, and grid decarbonization meet in measurable requirements.
