Lighting
Lighting in Blender is measured in Watts, but this is not light-bulb energy, but radiant flux, a measure of brightness. Below is a table of realistic values.
For artificial light sources, divide the lumen rating by the luminous efficacy to get the appropriate value.
For outdoor conditions, directly use the Radiant flux value given.

Common Lighting Radiant Flux Luminous Efficacy
| Light Source Type | Luminous Efficacy (lm/W) |
|---|---|
| Incandescent Bulb | 10-17 |
| Halogen Bulb | 16-24 |
| Compact Fluorescent Lamp (CFL) | 45-75 |
| LED Bulb | 80-100+ |
| Metal Halide Lamp | 65-115 |
| High-Pressure Sodium Lamp | 70-100 |

Common Outdoor lighting conditions Radiant Flux
| Light Source Type | Radiant Flux (W/m²) | Illuminance (lux) |
|---|---|---|
| Sunny Day | ~1000 W/m² | 100,000-130,000 |
| Cloudy Day | ~100-500 W/m² | 1,000-5,000 |
| Full Moon Night | ~0.0001-0.0003 W/m² | 0.1-0.3 |
| New Moon Night Conditions | ||
| Clear Sky, No Light Pollution | ~0.00002 W/m² | 0.002-0.003 |
| Clear Sky, High Light Pollution | ~0.00001 W/m² | 0.001-0.002 |
| Cloudy Sky, No Light Pollution | ~0.000005 W/m² | 0.0005-0.001 |
