Pick by Light is a light-directed order-picking system. LED indicators installed above storage locations show employees where to pick an item and what quantity is required for the order. Operators do not need to check paper documents or search for products across the warehouse. They simply follow the light prompts and confirm each pick. The solution includes indicators, confirmation buttons, a central controller and software.

The UIS Pick-to-Light system
Pick by Light is an order picking system that uses light indicators to guide operators to the correct locations on shelves or bins, improving picking speed and accuracy. Pick by Light technology simplifies the order picking process by guiding workers with visual cues, reducing errors, increasing efficiency, and minimizing the need for extensive employee training, making warehouse operations smoother. In addition, Pick-to-Light can be effectively implemented in environments such as a Postoffice, where fast and accurate sorting of parcels is essential for customer satisfaction.
The Pick-by-Light (or Put to Light / Pick2Light / PbL / PtL) is a paper-free order picking process that follows the “operator to goods” principle. During the picking of items, PTL systems plan an optimal route that allows the operator to move quickly from one item to another.
Using the UIS Pick-Light system, the operator is guided directly to the destination by an optical signal, with the full quantity of items that must be picked up are displayed on a screen.
When items are retrieved from the bin and the inventory is verified, pressing a confirmation button completes the process. The employee is then directed to the next storage locations until the order is fully processed. If the inventory in the compartment is incorrect, it can be adjusted using the correction key. This ensures a fast, accurate, and careful handling of customer orders.
The UIS company offers systems for various needs. The PbL is particularly advantageous in places with high-value goods and is also useful where open solutions or combinations with radio systems can be implemented.
The UIS P-to-L systems can feature multi-color indications. In combination with programming this enables the development of algorithms where multiple employees can work on the same order or where one operator can fulfill several orders.
The UIS Pick system is a new benefit for your business
By implementing this system, businesses can increase the number of orders processed daily while reducing operational costs associated with the fulfillment processes.
The Pick-by-Light is a technological solution aimed at improving efficiency and speeding up the assembly and sorting processes in warehouses. Its core functionality relies on LED displays and indicators placed in designated compartments on shelving units. For large logistics centers, the solution can also be integrated with a Yard Management System, ensuring seamless coordination between internal order picking and the management of inbound and outbound vehicles.
The UIS latest equipment integrates modern technologies and software, consisting of modular shelving with light indicators and additional devices like scanners and barcode printers.
This system addresses several issues related to manual order picking in warehouses. It saves time by providing workers with precise information about item locations and quantities in specific compartments.

Frequently Asked Questions
What is Pick by Light?
How is Pick by Light better than handheld terminals or paper pick lists?
When using paper pick lists, operators spend time locating storage positions and checking individual items, while errors may only be detected during final inspection. A handheld data terminal improves inventory tracking but still requires several additional actions: reading the task on the screen, finding the correct location and scanning every item.
Pick by Light removes these steps. The correct storage location lights up automatically, the indicator displays the required quantity, and the operator confirms the pick with a single button press. This increases picking speed by 50% and minimises the risk of selecting the wrong product or quantity.
How long does it take to train employees to use the order-picking system?
Training takes very little time, which is one of the key advantages of Pick by Light. The operating principle is intuitive: employees follow the light indicators, pick the specified quantity and confirm the action by pressing a button. There is no need for lengthy training or for employees to memorise product locations. New team members can therefore begin working almost immediately. This is particularly valuable during seasonal recruitment when the warehouse workforce needs to expand quickly.
At what daily order volume does it make sense to implement Pick by Light?
Pick by Light is generally suitable for operations processing approximately 300–500 orders per day or more. At lower volumes, the payback period may be longer. The system is particularly effective for e-commerce, pharmaceutical operations and fulfilment centres that handle a large number of small product lines and experience seasonal peaks.
