Because of the heat sink in the base light doesn t disperse downwards as much as a typical incandescent candelabra bulb.
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.
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.
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.
The wattage will be between 13 and 15 watts.
Additionally a 6 to 8 watt led light corresponds to a 13 to 15 watt cfl bulb.
