I intended to use this item after purchasing it, but I decided not to because the light fixture was an incandescent bulb. I am now listing it for sale. Please refrain from purchasing if you are concerned, as the item has been handled by a person once. I was planning to use it, so I discarded the box. There is a slight smudge-like stain, so I have reduced the price. Please refrain from purchasing if you are looking for a perfect item. 【Product Description】 ● [LED] Recessed Dimming Switch C (Single-pole/3-way) (Hotaru Switch C) (Compatible with LED only 1.6A) (Rotary type) (Lower limit illuminance setting function) (White) ● Compatible with Panasonic dimmable LED bulbs.
