Questions Fréquentes
What is the difference between lumens and lux?
Lumens measure total light output from a source. Lux measures how bright a surface is. The same number of lumens spread over a larger area produces fewer lux.
How many lumens do I need for a room?
Kitchens and workspaces need 300-500 lux. Living rooms need 100-300 lux. Bedrooms need 50-150 lux. Calculate: Lumens needed = Lux target x Area in m².
