It seems like you’re describing a specific chandelier with the following specifications:
- Diameter (D): 800 millimeters (80 centimeters)
- Height (H): 460 millimeters (46 centimeters)
- Material: FGD (presumably a type of material) + Blue (indicating the color of the chandelier)
A chandelier with a diameter of 800 millimeters and a height of 460 millimeters is a relatively large fixture, suitable for rooms with higher ceilings or spaces where a prominent lighting feature is desired. The combination of materials, such as FGD, and the blue color suggest a unique and potentially artistic design.
