These are my ABCO 100watt Smart Bulb four level dimmer bulbs. This bulb dims four different levels! The way this works is by a microchip in the base of the bulb. The microchip is made by BEACON Technology. This is how it is done How the four level dimmer feature works: (This is from the back of the box that each bulb came in) Turn your Smart Bulb on as you would any other bulb. Each OFF and ON motion of the switch will reduce the light intensity to the next level. At the last level, OFF and ON will return your bulb to full brightness. These bulbs were made in 1994 in Taiwan. Follow me on other Social Media!
