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 sb = 10,000 lm
1 lm = 0 sb
例子:
将15 stilb转换为流明：
15 sb = 150,000 lm
| stilb | 流明 |
|---|---|
| 0.01 sb | 100 lm |
| 0.1 sb | 1,000 lm |
| 1 sb | 10,000 lm |
| 2 sb | 20,000 lm |
| 3 sb | 30,000 lm |
| 5 sb | 50,000 lm |
| 10 sb | 100,000 lm |
| 20 sb | 200,000 lm |
| 30 sb | 300,000 lm |
| 40 sb | 400,000 lm |
| 50 sb | 500,000 lm |
| 60 sb | 600,000 lm |
| 70 sb | 700,000 lm |
| 80 sb | 800,000 lm |
| 90 sb | 900,000 lm |
| 100 sb | 1,000,000 lm |
| 250 sb | 2,500,000 lm |
| 500 sb | 5,000,000 lm |
| 750 sb | 7,500,000 lm |
| 1000 sb | 10,000,000 lm |
