Duct rail pendant light, - Type: For duct rail - Material: Glass - Color: Clear, cracked finish - Power source: Electric Thank you for looking. I am selling this item as it was purchased by mistake and is almost unused. It comes with a light bulb (warm, incandescent color), so you can use it right away. It is "for duct rail." Please note that it is not for ceiling installation. The cord length is adjustable. Please check the images for the size. I have borrowed images from the purchase site. It's made of glass, not plastic, so the texture is very cute.
