This product is an LED bulb that can be switched to three colors: "white", "lunch white", and "bulb color" simply by turning the lighting switch on and off. You can choose the white color that is easy to see when cleaning or cooking, the neutral white color when you concentrate on studying, and the warm light bulb color before going to bed, depending on your lifestyle.
When the switch is turned on, white (default color) lights up first, and when the switch is operated quickly while the switch is on, the color of the light changes in order. It will be reset in 10 seconds after it goes out, and will return to white when it is turned on again.
There are three types of lineup: ball type 100W equivalent (3,480 yen / tax not included, same below), ball type 60W equivalent (2,980 yen), and wide light distribution type 60W equivalent (2,480 yen). All E26 caps.
