APick-to-Light (PTL)system is a semi-automated order fulfillment technology that uses light displays to guide workers to the correct picking locations. According to CLT’s “Order Processing” materials, PTL increasesspeed and accuracyby illuminating the bin or slot containing the required item, while digital displays show quantity and confirmation buttons verify completion. This eliminates paper pick lists and reduces errors associated with manual documentation. Unlike systems that rely on visual searches or scanning after the fact, PTL enables real-time verification at the point of pick. The CLT curriculum emphasizes that these systems improve worker productivity and throughput while reducing training time. PTL technology integrates with the Warehouse Management System (WMS) to automatically update inventory balances and order status once confirmed.
