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.

  1. 01Lumens = 10W x 90 lm/W = 900 lumens
  2. 02Incandescent equivalent = 900 / 14 = 64W
