公式
## Lumens to Lux **Lux = Lumens / Area (m²)** Lumens measure total light output. Lux measures illumination intensity on a surface. ### Typical Light Levels | Condition | Lux | |---|---| | Full sunlight | 100,000 | | Overcast day | 10,000 | | Office lighting | 300-500 | | Living room | 50-200 | | Full moon | 0.25 |
计算示例
An 800 lumen bulb illuminating a 10 m² room.
- 01Lux = 800 / 10 = 80 lux
- 02Foot-candles = 80 x 0.0929 = 7.4 fc
常见问题
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.
