Technical Notes: Wattage vs. Lumens
Wattage is strictly a measure of power consumption, not brightness. For historical reasons, incandescent wattage became a proxy for brightness (e.g., a "60W bulb"), but this correlation breaks down with efficient technologies.
Engineering Rule of Thumb:
- Incandescent Luminous Efficacy: ~10-17 lm/W
- LED Luminous Efficacy: ~80-150+ lm/W
This 6x-10x efficiency factor is why a 9W LED can replace a 60W incandescent. Always verify the Lumen (lm) rating on specification sheets to ensure equivalent illumination.
