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: Merak, belonging to category: Post-Top Luminaire

### Response:
The Merak post-top luminaire is equipped with an LED module that can be exchanged without the use of tools. This special feature has great cost benefits as only the light source has to be replaced. The body can be reused and fitted with new drivers and light sources. The tempered safety glass prevents dirt from building up on the lenses. A buffer stops dust and water from getting in and offers added security as the electrical current is automatically interrupted as soon as the luminaire is opened.
