Watts to Lumens Converter — Formule
## Watts to Lumens
**Lumens = Watts x Luminous Efficacy (lm/W)**
### Typical Efficacy by Bulb Type
| Bulb Type | Efficacy (lm/W) |
|---|---|
| Incandescent | 12-17 |
| Halogen | 16-24 |
| CFL | 50-70 |
| LED | 80-120 |
| High-efficiency LED | 100-150 |
A 10W LED produces roughly the same light as a 60W incandescent bulb.

Exemple Résolu
10 watt LED bulb.
- Lumens = 10W x 90 lm/W = 900 lumens
- Incandescent equivalent = 900 / 14 = 64W
