From the table, a 9-watt incandescent bulb is equivalent to a 1-watt LED bulb. A 60-watt LED equivalent is 7-9 watts. A 100-watt incandescent bulb produces 1600 lumens of light, while a 12-14 watt LED gives off the same. A 150-watt incandescent bulb produces 2600 lumens of light, while an 18-23 watt LED gives off the equivalent.

Use a 7:1 ratio as a rough guide when selecting an LED bulb to replace an incandescent bulb. For example, if you wanted to replace a 60-watt incandescent bulb, what wattage LED bulb would be roughly equivalent? Using the 7:1 ratio, simply divide 60 watts by 7 to get roughly 9 watts.

Lightbulb brightness in general is measured in lumens (not watts). Bulb manufacturers include this information and the equivalent wattage right on the packaging. Common terms are ‘soft white 60,’ ‘warm light 60,’ and ’60 watt replacement.’

Equivalent wattage is a term used to describe the brightness of an LED bulb in comparison with incandescent lamps. For example, when you see the phrase “60W equivalent” on an LED light bulb, it doesn’t mean it consumes 60W. Instead, it means the bulb produces as many lumens as a 60W incandescent, which is 800 lumens.
