The conversion of lumens to watts uses the formula: Watts = Lumens / Efficiency (lumens per watt) For example, an LED with an efficiency of 75 lumens per watt would require 5. 41 watts to produce 460 lumens. 460 lumens / 85 lumens per watt = 5. For our lightbulbs, the lumen defines the perceived brightness of a specific bulb (such as an LED fixture). The following table shows a range of luminous efficacies for different light bulbs: Luminous efficacies of different light bulbs. Various factors affect brightness, including the lumen output which is crucial in determining the effectiveness of solar. .
