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 = 1 lm/cm²
1 lm/cm² = 1 sb
例子:
将15 stilb转换为每平方厘米的管腔：
15 sb = 15 lm/cm²
| stilb | 每平方厘米的管腔 |
|---|---|
| 0.01 sb | 0.01 lm/cm² |
| 0.1 sb | 0.1 lm/cm² |
| 1 sb | 1 lm/cm² |
| 2 sb | 2 lm/cm² |
| 3 sb | 3 lm/cm² |
| 5 sb | 5 lm/cm² |
| 10 sb | 10 lm/cm² |
| 20 sb | 20 lm/cm² |
| 30 sb | 30 lm/cm² |
| 40 sb | 40 lm/cm² |
| 50 sb | 50 lm/cm² |
| 60 sb | 60 lm/cm² |
| 70 sb | 70 lm/cm² |
| 80 sb | 80 lm/cm² |
| 90 sb | 90 lm/cm² |
| 100 sb | 100 lm/cm² |
| 250 sb | 250 lm/cm² |
| 500 sb | 500 lm/cm² |
| 750 sb | 750 lm/cm² |
| 1000 sb | 1,000 lm/cm² |
| 10000 sb | 10,000 lm/cm² |
| 100000 sb | 100,000 lm/cm² |
