A common range of objects illumination
Object illumination can vary based on a range of different factors. Refer to the table below to estimate the object illumination depending on various conditions:
Light condition | Typical lux |
|---|---|
Clear, sunny day | More than 100 000 lux (sun angle 55°) |
Sunny day with slight overcast | 70 000 lux |
Overcast day | 20 000 lux |
Early morning | 500 lux |
Twilight | 4 lux |
Clear night, full moon | 0.2 lux |
Clear night with a moon in any phase other than the full moon | 0.02 lux |
Night, moon in clouds | 0.007 lux |
Clear night (no moon) | 0.001 lux |
Night with slight overcast (no moon) | 0.0007 lux |
Dark, cloudy night | 0.00005 lux |
Indoors, no windows, with artificial illumination | 100 – 200 lux |
Well-illuminated indoor spaces, offices | 200 – 1000 lux |
