Put-to-Light (PTL) System: Say Goodbye to Traditional Methods and Achieve Fast, Flawless Order Sortation

What is a Put-to-Light System?

For e-commerce fulfillment centers processing massive order volumes or retailers managing diverse inventory, quickly and accurately sorting goods into their correct locations remains a critical operational challenge.

The Put-to-Light (PTL) system is a visual, light-directed technology specifically designed for "batch picking and sortation" (often utilizing a Put Wall) and precise warehouse putaway. While a Pick-to-Light system instructs workers on where to take items from, a Put-to-Light system guides them on where to place the items they are holding.

The 4 Core Components of the System:

• Barcode Scanners: Handheld scanners or wearable ring scanners used to read product barcodes.

• LED Light Modules: Installed directly on Put Walls, order totes, or warehouse racks.

• Digital Displays & Confirmation Buttons: Displays the exact quantity to be placed and features a button for the worker to confirm the action.

• Smart Sortation Software: Integrates in real-time with your company's WMS (Warehouse Management System) or ERP for seamless data matching and task allocation.

The Highly Intuitive Workflow: The worker picks up an item and scans its barcode ➔ The system instantly illuminates the LED light at the correct order bin or storage location ➔ The worker follows the light, places the designated quantity into the bin ➔ The worker presses the button to confirm.

4 Core Advantages of the Put-to-Light System

Modular Design for Easy Installation

A Put-to-Light system requires no massive structural modifications to your warehouse. The electronic tag modules can be easily clipped or bolted onto existing carton flow racks, static shelving, or even mobile Put Carts. With simplified wiring and high scalability, businesses can effortlessly expand or reduce their Put Wall configurations based on peak season demands.

Paperless Operations & Zero Learning Curve

Traditional sortation relies on workers holding printed pick lists and visually matching order numbers to items—a process highly susceptible to fatigue and human error. By implementing Put-to-Light, the complex logic of matching items to orders is entirely handled by the backend system. Workers simply follow the lights. Even temporary or part-time staff with zero experience can achieve high-efficiency sorting within 10 minutes of training.

Low Investment Threshold & High ROI

For many SMEs, investing in large-scale, rigid automation equipment (like Sortation Systems) can be prohibitive in terms of cost and floor space. The electronic Put-to-Light system delivers exceptional sortation throughput comparable to heavy machinery but at a fraction of the cost. By drastically reducing processing time and labor requirements, businesses can achieve a rapid Return on Investment (ROI).

Built-in Error-Proofing for Flawless Accuracy

"Mis-sorts" are the primary cause of customer complaints and costly returns. The Put-to-Light system features strict error-proofing (Poka-yoke) mechanisms. The system will only prompt the next step once the item is placed in the correctly illuminated bin and confirmed. This visual guidance reduces the error rate to near-zero, dramatically improving order fulfillment accuracy.

Ideal Application Scenarios for Put-to-Light

The unique advantages of the Put-to-Light system make it perfectly suited for the following high-complexity environments:

• E-commerce & Logistics Order Sortation (Put Walls): This is the most common application. Workers perform "batch picking" for multiple orders and bring the consolidated items to a Put Wall. By simply scanning each item, the system lights up the specific cubby representing a customer's order. This seamlessly streamlines the complex process of order splitting and consolidation without ever needing to cross-reference a paper list.

• Warehouse Putaway & Reverse Logistics (Returns): When a warehouse receives a massive influx of mixed goods from suppliers or processes customer returns, sorting items quickly typically requires highly experienced staff. With Put-to-Light, after scanning the new or returned item, the corresponding storage rack light flashes, guiding the worker to the exact putaway location. This prevents inventory pile-ups and stock misplacement.

• Supermarket & Retail Replenishment: Supermarkets often utilize tight backroom storage. When mixed pallets arrive from central distribution centers, retail staff can use PTL technology to rapidly sort diverse items (e.g., separating snacks, chilled goods, and daily necessities) onto specific staging carts based on aisle numbers. This not only boosts efficiency but also prevents shrinkage and expired goods caused by misplacing items.

Put-to-Light FAQ

Q1: What is the exact difference between Put-to-Light and Pick-to-Light?

Both use similar hardware but operate in reverse. Pick-to-Light is for "Outbound Order Picking" (the system tells you which rack to go to and how many items to grab to fulfill an order). Put-to-Light is for "Inbound Sorting/Allocation" (you have an item in hand, and the system tells you which order bin or rack to put it into). They can be combined to create a fully paperless warehouse ecosystem.

Q2: Can this system be installed on mobile carts?

Yes. As long as the cart is equipped with a battery pack and independent electronic tags, workers can push the "Smart Put Cart" through the warehouse, performing simultaneous sortation for multiple orders on the go. This offers maximum operational flexibility.

Q3: If a module breaks, will it halt the entire warehouse operation?

Our tag modules utilize an independent, plug-and-play design. If a single light or button malfunctions, you can hot-swap it with a new module in seconds without shutting down or rebooting the system. Additionally, the software backend supports manual override modes, ensuring your operations never experience downtime.
