Why More E-commerce Warehouses Are Switching to Pick-to-Light Systems in 2026

Over the past few years, the rapid growth of e-commerce has transformed warehouse operations around the world. Customers expect faster delivery, higher order accuracy, and real-time inventory visibility, which puts enormous pressure on warehouse fulfillment processes.

In 2026, many e-commerce and retail warehouses are turning to Pick-to-Light systems as one of the most effective solutions to improve picking efficiency while controlling labor costs. 

The Growing Challenge of Order Picking

Order picking is one of the most labor-intensive and time-consuming processes in warehouse operations. In many distribution centers, picking activities account for up to 50–60% of total warehouse operating costs.

At the same time, warehouses are facing several major challenges:

• Increasing order volumes from online sales
• A growing number of SKUs
• Labor shortages in logistics operations
• Rising labor and training costs
• Traditional picking methods using paper lists or handheld scanners often struggle to keep up with these demands.

How Pick-to-Light Systems Improve Warehouse Efficiency

Pick-to-Light (PTL) systems use LED indicators and confirmation buttons installed on storage shelves to guide workers directly to the correct picking location.

When an order is released from the warehouse management system (WMS), the corresponding lights illuminate to show operators where to pick and how many items to pick.

This simple visual guidance significantly improves warehouse performance.

Faster Picking Speed

Workers no longer need to search for product locations or read picking lists. The system visually guides them to the correct shelf location, reducing walking and searching time.

Many warehouses report 30–50% improvements in picking productivity after implementing Pick-to-Light systems.

Higher Order Accuracy

By clearly indicating the correct location and quantity, Pick-to-Light systems greatly reduce human errors. This can help warehouses achieve near-perfect order accuracy, improving customer satisfaction and reducing costly returns.

Shorter Training Time

One of the biggest advantages of Pick-to-Light systems is simplicity. New employees can quickly understand the process:

1. Follow the light
2. Pick the item
3. Press the confirmation button

This intuitive workflow reduces training time and helps warehouses scale operations quickly during peak seasons.

A New Industry Trend: Compact and Cost-Effective PTL Devices

As warehouse automation becomes more widespread, companies are increasingly looking for simpler and more cost-effective Pick-to-Light hardware.

Traditional PTL modules sometimes include displays, multiple buttons, or complex interfaces. However, many warehouses today prefer compact light modules with a single confirmation button.

This new design trend offers several advantages:

• Smaller devices for high-density shelving
• Lower hardware costs for large-scale deployments
• Easier installation and maintenance
• Simpler operation for warehouse workers

For warehouses with thousands of picking locations, these improvements can significantly reduce the total cost of ownership (TCO).

Industries That Benefit Most from Pick-to-Light Systems

Pick-to-Light technology is widely used in industries that require high-speed and high-accuracy order fulfillment, including:

• E-commerce fulfillment centers
• Retail distribution warehouses
• Pharmaceutical logistics
• Spare parts distribution
• Manufacturing assembly operations

These environments typically involve high order volumes and large product assortments, where traditional picking methods become inefficient.

The Future of Warehouse Order Fulfillment

As global supply chains continue to evolve, warehouses are investing more in smart automation technologies that improve efficiency while keeping operations flexible.

Pick-to-Light systems are expected to remain one of the most practical solutions for semi-automated order picking, especially for operations that require speed, accuracy, and scalability.

By combining human workers with intelligent visual guidance, warehouses can dramatically improve productivity without the complexity and high costs associated with full robotic automation.
