Lumens are the amount of light produced by a bulb or fixture. More lumens translates to a brighter light. As LED lighting continues to grow and expand, lumens are taking the place of wattage when it comes to shopping for bulbs. Shopping by wattage is beneficial for knowing the amount of power that a bulb will consume, but it will only help you guess their light output. Shopping by lumens eliminates any guesswork.
To determine equivalent incandescent wattage based on LED lumen output, simply remove the last number in the lumen value.
For example:
1,000 lumen LED bulb = 100-watt incandescent bulb
