How many lumens is a 22 watt LED bulb?
A 22-watt LED bulb is much brighter than a 60-watt incandescent bulb, because the 22-watt LED produces 1600 lumens, where the 60-watt incandescent produces only 800. Clearly, in the case of measuring LEDs, lumens are the better measurement.
How many lumens do you need for your next light bulb?
Use this chart to determine how many lumens you’ll need from your next light bulb. For example, if you typically purchase 60W incandescent bulbs, which produce about 700-800 lumens, consider purchasing a lower energy alternative like a 42W halogen bulb, 12W CFL, or even a 10W LED bulb to achieve the same brightness.
What is the ratio of led to incandescent?
This 4:1 ratio is a rough guide of how to calculate which LED bulb to use when replacing an incandescent bulb. For example, if you need to replace a 60-watt incandescent bulb with an LED bulb, then divide 60 watts by 4 to get 15 watts – that will be a good estimate.
