This is a Z-Light by Yamada Lighting. It's the clamp-on type. I think it's been around 10 years. Operation has been confirmed. There is no box or instruction manual, everything is shown in the photos. I tried to take good care of it, so I don't think the condition is bad, but please check the photos for the condition of the product. However, since it is a used item, please refrain from purchasing if you are concerned about minor details.
