Amazon Price on April 21st: ¥6,299 (tax included) This is a listing for the LVWIT Filament Bulb E26 Base LED Edison Bulb, 4.5W (equivalent to 30W), dimmable and color-adjustable, with a remote control. I purchased this new on Amazon and used it in an indoor pendant light until recently. Both the remote control and the light bulb have been used until recently, so their operation has been confirmed. The remote control and the light bulb were purchased as a set, so they were paired. I have discarded the box and instruction manual, so they are not included.
