WHAT IS a lights-out warehouse?

A “lights-out warehouse” is a fully automated warehouse that requires little to no human presence on the shop floor, allowing operations to run without lighting or staff onsite. Because of this, it is sometimes also referred to as a “dark warehouse”.

These warehouses rely on advanced automation – such as conveyors, sorters, pouch systems, and robotic picking – to manage storage, retrieval, sorting etc. for order fulfilment.

Also known as:

Dark warehouse
Autonomous warehouse

HOW DOES a lights-out warehouse WORK?

Lights-out warehouses combine completely automated material handling equipment with advanced control software such as Warehouse Management Systems (WMS) and/or Warehouse Control Systems (WCS).

Key features of a dark warehouse include:

Automated storage – ASRS, shuttle systems, and robotics manage inventory.
Automated transport – conveyors, sorters, and pouch systems move goods across the facility.
Automated picking – robotic or goods-to-person systems handle order selection.
Software integration – WMS and WCS synchronise data with automation to optimise flows.
Predictive analytics – AI-driven insights anticipate demand, faults, and maintenance needs.

BENEFITS OF a lights-out warehouse

Efficiency: Lights-out warehouses operate 24/7 without interruption.
Accuracy: Reduces picking and handling errors.
Labour optimisation: Minimises reliance on human labour in high-cost or labour-scarce markets.
Energy savings: Requires little or no lighting and can optimise HVAC use.
Safety: Removes people from potentially hazardous environments.
Scalability: Handles high throughput and seasonal peaks.

FAQ ABOUT lights-out warehouses

Why is it called a lights-out warehouse?

It’s called a lights-out warehouse because human workers are not needed for most operations, the facility can run without lighting – relying solely on automation.

What technologies enable a lights-out warehouse?

Lights-out warehouses rely on conveyors, sorters, pouch systems, ASRS, robotic picking, and software platforms like WMS and WCS.

What are the challenges of a lights-out warehouse?

Challenges of lights-out warehouses include high upfront investment costs, complex system integration, and the need for robust IT infrastructure. Lights-out warehouses also require advanced maintenance expertise, and handling unexpected exceptions without human presence can be difficult.

What industries use lights-out warehouses?

E-commerce, retail, and parcel logistics are expected to be the first major adopters of lights-out warehouses, driven by their need for high throughput, accuracy, and scalable operations.

What are the future impacts of a lights-out warehouse?

Lights-out warehouses are set to reshape supply chains by enabling round-the-clock operations, reduced labour dependency, and greater resilience to workforce shortages. As automation and AI mature, lights-out warehouses are expected to become more common, especially in e-commerce and parcel logistics.

How to start a lights-out warehouse?

Most businesses begin with a phased approach, automating key processes such as picking and sortation before moving towards fully lights-out operations. Success depends on choosing scalable automation, strong integration with WMS/WCS, and reliable partners such as BEUMER Group to align systems. Careful planning, simulation, and testing are critical to reduce risks and ensure a smooth transition.
