Illuminance is the total luminous flux incident on a surface per unit area. It is measured in lux (lx).
1 lm/W = 1 lx·h
1 lx·h = 1 lm/W
Example:
Convert 15 Lumen per Watt to Lux Hour:
15 lm/W = 15 lx·h
| Lumen per Watt | Lux Hour |
|---|---|
| 0.01 lm/W | 0.01 lx·h |
| 0.1 lm/W | 0.1 lx·h |
| 1 lm/W | 1 lx·h |
| 2 lm/W | 2 lx·h |
| 3 lm/W | 3 lx·h |
| 5 lm/W | 5 lx·h |
| 10 lm/W | 10 lx·h |
| 20 lm/W | 20 lx·h |
| 30 lm/W | 30 lx·h |
| 40 lm/W | 40 lx·h |
| 50 lm/W | 50 lx·h |
| 60 lm/W | 60 lx·h |
| 70 lm/W | 70 lx·h |
| 80 lm/W | 80 lx·h |
| 90 lm/W | 90 lx·h |
| 100 lm/W | 100 lx·h |
| 250 lm/W | 250 lx·h |
| 500 lm/W | 500 lx·h |
| 750 lm/W | 750 lx·h |
| 1000 lm/W | 1,000 lx·h |
| 10000 lm/W | 10,000 lx·h |
| 100000 lm/W | 100,000 lx·h |
