This is a pendant light from Takizumi. The brightness is suitable for approximately 6 tatami mats (about 100 square feet). It's very simple, but it's a reliable, made-in-Japan product. I've had it for about 5 or 6 years, but there's no noticeable damage, as it's just for lighting. It can be easily installed on a ceiling hook. You can install it without any problems, even by yourself. Price is not negotiable.
