照明是每单位区域表面上的总发光通量。它以Lux（LX）为单位。
1 lm = 1 cd/m²
1 cd/m² = 1 lm
例子:
将15 流明转换为每平方米烛台：
15 lm = 15 cd/m²
| 流明 | 每平方米烛台 |
|---|---|
| 0.01 lm | 0.01 cd/m² |
| 0.1 lm | 0.1 cd/m² |
| 1 lm | 1 cd/m² |
| 2 lm | 2 cd/m² |
| 3 lm | 3 cd/m² |
| 5 lm | 5 cd/m² |
| 10 lm | 10 cd/m² |
| 20 lm | 20 cd/m² |
| 30 lm | 30 cd/m² |
| 40 lm | 40 cd/m² |
| 50 lm | 50 cd/m² |
| 60 lm | 60 cd/m² |
| 70 lm | 70 cd/m² |
| 80 lm | 80 cd/m² |
| 90 lm | 90 cd/m² |
| 100 lm | 100 cd/m² |
| 250 lm | 250 cd/m² |
| 500 lm | 500 cd/m² |
| 750 lm | 750 cd/m² |
| 1000 lm | 1,000 cd/m² |
| 10000 lm | 10,000 cd/m² |
| 100000 lm | 100,000 cd/m² |
