Below is an instruction that describes a task. Write a response that appropriately completes the request.

### Instruction:

Create a detailed description for the following product: Billie, belonging to category: Luminaire

### Response:
Following a classic design language, this pendant luminaire is surprising on account of its hollow centre. The internal geometry has been optimized to increase the reflective surface for improved light diffusion. This creates effective lighting that is pleasingly glare-free regardless of the installation height or lumen output level. The inner shade is matt white, while the exterior shade is available in a choice of lightly textured black, white or any RAL colour.
