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