| Condition | Typical illuminance | Planning note |
|---|---|---|
| Direct sun | 32,000-100,000 lx | Record glare, heat and direct-sun exclusion before using the reading in a daylight-factor check. |
| Full daylight, no direct sun | 10,000-25,000 lx | Useful outdoor reference scale; indoor task values still depend on aperture, shading and reflectance. |
| Overcast midday | 1,000-2,000 lx | Good comparison condition for repeat readings when direct sun would distort the task-plane record. |
| Sunrise or sunset | 300-500 lx | Short-lived condition; record time and orientation before treating it as useful working light. |
| Heavy cloud or deep shade | 50-200 lx | Often below task-light targets; record the remaining electric-light target separately. |
