LED Lumens To Watts Conversion Chart

Lumens are the new unit of measurement for light bulbs. For many years, we have been buying light bulbs according to wattage. With the low-wattage and energy efficient light bulbs like Compact Fluorescent Lamps (CFLs) and Light-emitting diode (LEDs) become easily available at an affordable price, buying bulbs based on watts has become less prevalent.

Instead of focusing on wattage, which measures power use, many manufacturers are now labelling their energy efficient blubs according to lumens, which measure light output. Lumens are actually a more accurate measurement of how bright your light will be.


Measure and labelling light output instead of energy use makes it easier for you to find the right energy efficient bulbs for your space. By using the chart above, you can determine how many lumens you need for your next light bulb. For example, if you typically purchase 40W incandescent bulbs, which produce about 400-500 lumens, consider purchasing a lower energy alternative like 30W halogen bulb, 8W CFL, or even a 5.5W LED bulb to achieve the same brightness.
