Light Bulbs - Watts or Lumens?
In the past, the strength of light bulbs was measured in watts, which is actually a measure of power. This isn’t a useful unit of measurement for new energy-saving light bulbs, which consume much less power than old-style incandescent light bulbs. So because comparisons based on wattage are no longer meaningful, the strength of new energy-saving light bulbs is expressed in lumens, which measures instead the amount of light they produce. The higher the number of lumens, the brighter the light.
There isn’t necessarily a correlation between lumens and watts because they measure different things. But as a rough example a Standard 40W Incandescent is equivalent to an 6W LED.
