The general light illuminating a room. Lumens, the scientific measurement, describes light intensity based on the illumination provided by a single candle. Wattage is a practical way of measuring light. Take a look at the packaging the next time you buy bulbs and you'll notice both watt and lumens ratings. For instance, a typical 60W incandescent bulb provides approximately 840 lumens of light.
Fluorescent bulbs provide considerably more light than incandescents.
For example, a typical 40W fluorescent bulb has a lumens rating of around 3,000. Today's Homeowner, a division of Times Mirror Magazines. Privacy policy .
