Watts Vs Lumens

Lumens and watts are both measurements related to light, but they measure different things:

1. Watts (W): Watts measure the amount of electrical power consumed by a light bulb or device. In the past, people often used wattage as a way to gauge the brightness of a bulb, with higher wattage bulbs generally producing more light. However, this is no longer an accurate way to assess brightness due to energy-efficient LED bulbs, which produce the same or more light while using significantly fewer watts.

2. Lumens (lm): Lumens measure the actual brightness or light output produced by a light source. It tells you how much light is emitted by a bulb or fixture. The higher the lumens, the brighter the light. 

In summary, watts indicate power consumption, while lumens indicate brightness. When choosing lighting, it's better to focus on lumens to ensure you get the desired level of brightness while considering energy efficiency, rather than relying solely on wattage as was common in the past.
