Our A-19 A LED light bulbs come in 6, 7, 8, 9 and 12 watts and directly replaces 60 watt incandescent or CFL light bulbs and do not require any form of adapter because they are screw base bulbs. LED bulbs provide the same brightness as the incandescent bulbs and come in a range of color temperature: warm, neutral and cool. Simply swap the light bulb – no additional accessories needed. These LED bulbs use up to ten times less electricity than conventional incandescent lights and last up to 25 years or 50,000 hours. They are environmentally safe with no hazardous materials and no UV or IR radiation.
