【Note: Controlled by wall switch, remote control not included.】 I purchased this from another site, but I gave up on installing it myself. It's made in China. It's not an integrated type. You need to attach the top part to the ceiling and then join the bottom part with a screwdriver and screws, so I think you'll need two people to do the work. When installing, work with the wall switch turned off. The photos show the item after it has been opened. I purchased three in total, so I will ship the unopened ones with the shipping label directly on the box, in a 120-size package. The box is approximately 45 x 45 x 13 cm. You can purchase multiple, including the opened one. I will copy and paste the site's description below. ■■■■■■■■■■■■■■■■■■■ Adjustable from daylight, neutral white, and warm white using the wall switch; color temperature can be adjusted from warm to daylight.
