Let's imagine that you are looking for an extremely bright bulb that emits 1,300 lumens. For an LED bulb, producing 1,300 lumens will require around 15 watts of power. However, for a less-efficient halogen bulb, over 60 watts of power are likely to be required to produce the same brightness. Same level of brightness, different amount of power ...
First, you will enter 250 as the value of power in watts. Select halogen lamp in the options provided and then click the ‘Calculate’ button. The luminous efficacy in lumens per watt is displayed automatically after selecting the light source. The luminous flux result in lumens will be; 5000 lumen (lm) Formula of converting watts to lumen
In the calculator, select Watts to Lumens as the conversion type, enter the value 35 and select the item Light bulb for comparison. After a click on the calculate button the luminous flux is displayed in lumens. The result should serve as a guideline for the brightness of the new LED lights.
The conversion of watts to lumens uses the formula: Lumens = Watts x Efficiency (lumens per watt) For example, an LED with an efficiency of 75 lumens per watt using 5.41 watts will create a luminous flux of 460 lumens. 460 lumens = 5.41 watts x 85 lumens per watt.

The lumen is a measure of the total "amount" of visible light. The lumen is the SI derived unit of luminous flux (symbol: lm). Watts to lumens Formula:
May 3, 2024 · To convert 500 watts to lumens: Find the type of bulb to determine its luminous efficacy. Then multiply the wattage of the bulb with its luminous efficacy to obtain lumens. For example, if our 500 watts bulb has a luminous efficacy of 40 lm/W: The amount of light it can produce will be 500 × 40 = 20,000 lumens.
500. 2. 200. 1. 100. To convert the power consumption from Watts to Lumens, multiply the value in Watts by the luminous efficacy in lm/W. For example, if the power consumption is 10 W and the luminous efficacy is 100 lm/W, the luminous flux would be 10 W × 100 lm/W = 1000 lm. Similarly, for a power consumption of 5 W and the same luminous ...
