Meet the home accessory that actually places the 3-way light bulb with bulb sockets: the AMAZING 3-WAY LAMP ADAPTER. Each socket holds a standard single-function light bulb. The 2 bulbs together function as a 3-way bulb when the lamp uses the low, medium, or high setting. Lamp output is a choice of bulbs used. Moreover, the this lamp adapter saves both on bulb replacements costs and energy consumption. And replace burnouts with lower-cost, single-function light bulbs in lieu of a higher-cost 3-way light bulb each time. Also, a user-installed clip adds usage of the adapter in any single function lamp with an on-off switch offering both bulbs on or both bulbs off. Finally, this bulb uses a standard screw light bulb in the USA and Canada.
