Cfl light bulbs wattage equivalents.

Watts chart below to shop for the right light bulb for your space. Lumen wattage comparison. Incandescent equivalent in general a simple rule to follow to replace an incandescent with an equivalent in light output cfl bulb is to select the cfl bulb that has 1 4 watts compared with the replaced incandescent bulb. A 60 watt equivalent cfl bulb from philips for example consumes 13 watts and has a rated lifetime of 12 000 hours or about 11 years when lit for three hours a day but retails for only 1 50.

The chart below illustrates the amount of brightness in lumens you can expect from different wattages of light bulbs. The equivalent of a 13 watt compact fluorescent cfl light bulb is between 40 and 60 watts of power from an incandescent light bulb which corresponds to between 450 and 800 lumens. Designed to replace incandescent candelabra bulbs these flame tip leds deliver the equivalent light of 25 35 watt incandescent while only drawing 3 5 watts of electricity. Additionally a 6 to 8 watt led light corresponds to a 13 to 15 watt cfl bulb.

An equivalent compact fluorescents cfl bulb in light output lumens should consume only around 7 watts and leds approximately 6 watts. 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. Some cfl and led bulbs will put their wattage equivalents on the box while many don t so this chart should help give you a good idea of how bright your new bulb is going to be. Led bulbs require much less wattage than cfl or incandescent light bulbs which is why leds are more energy efficient and longer lasting than their competitors.

For example a correct replacement for a 60w incandescent bulb would be a 15 watt cfl bulb 60 1 4 15. A 40 watt incandescent filament bulb produces roughly 460 lumens. Because of the heat sink in the base light doesn t disperse downwards as much as a typical incandescent candelabra bulb. The wattage will be between 13 and 15 watts.
