Put to Light is an automated system for distributing items into warehouse cells or order locations. After an item is scanned, the light indicator highlights the correct cell. The operator places the item there and confirms the action. This allows goods to be sorted without knowing the warehouse layout or searching manually — the system guides the operator through the process.

Frequently Asked Questions
What is a Put to Light system?
How is Put to Light different from Pick by Light?
Pick by Light is used for picking items during order fulfillment: the operator takes the product from the highlighted cell. Put to Light works in the opposite direction: it helps distribute items into cells, orders, or sorting locations. Both systems can operate in parallel in the same warehouse and be integrated into one end-to-end process.
What minimum volume makes Put to Light worthwhile?
The system is effective for operations processing several hundred SKUs per shift. If a warehouse handles fewer than 200–300 items per day, the payback period may be longer. Put to Light is especially suitable for fulfillment centers and online stores with peak workloads and a large number of small orders.
How much does Put to Light implementation cost?
The cost depends on the number of modules and cells, the operation confirmation method, the need for integration with WMS/ERP, and the level of structural customization. The UIS team calculates the configuration after analyzing the current sorting process and performance requirements.
