You will find the suitable LED replacement in the 5th column of the same row. You can find the 13 watt CFL bulb in the 3rd row of the 4th column. Lumens to watts comparison of different lighting technologies Example Comparisons The values are average values of the respective lighting technology and vary by manufacturer. This table shows a comparison of the power consumption and the respective brightness of all common light sources. The result should serve as a guideline for the brightness of the new LED lights. After a click on the calculate button the luminous flux is displayed in lumens. In the calculator, select Watts to Lumens as the conversion type, enter the value 35 and select the item Light bulb for comparison. If you already have some LED lamps in the closer selection, you can convert their lumen value into the output (in watts) of previous lights.Įxample 2: You have a torchiere with two 35W bulbs and want to replace them with LED lights. So you can calculate how many lumens the new LED lamps should have based on your previous lighting.

This free online calculator will help you convert lumens to watts and vice versa. The Lumens to Watts Calculator helps you to compare the brightness of different light sources. The brightness in lumens is particularly important when using LED lamps. The lumen value can be used to compare the brightness of different lamps, irrespective of efficiency and lighting technology used. The lumen specification is often given in the short form lm.
For LED luminaires and illuminants, this must always be stated in the product description. This is the power emitted per second in the wave range of visible light. The unit lumen describes the luminous flux emitted by a lamp. This is possible because lamp A could achieve a better efficiency through higher quality components and therefore emits more light. For the comparability of LED lamps the brightness is indicated in lumens. Different components in various LED lamps lead to varying brightness with the same power consumption.įor example, a 5W LED illuminant of type A can light up much brighter than a second 5W LED lamp of type B. However, the wattage plays a minor role now and allows only a very rough conclusion on the actual brightness. The replaced lamp was just as bright as before and there was no need to worry about the correct brightness.įor LED lamps, the power consumption is also indicated in watts. If a 60W bulb fails, it could be simply replaced by a new 60W bulb. Here the wattage was the most important indicator for the brightness.
Old light sources such as incandescent bulbs or halogen lamps were easy to choose. Scroll to the lumens to watts calculator Convert lumens to watts
