In complex warehouses there are number of picking zones and picking locations. In such warehouses, there are number of orders and number of picks to be performed each hour and for this, warehouse staff must be fast and accurate so that customer orders are fulfilled with satisfaction.

Over the time, there have been a number of technological inventions in warehouse systems and one of those is the “pick to light” system.

Pick to light is one of the advance technology of picking which provides an accurate method of picking and assembling of products and it is completely paperless system.

How Pick To Light Works

The basic system include lights above the racks or bins, and at each product location there is alphanumeric display. Barcode of particular order is assigned to picking container. Container then goes to the picking zone with help of conveyor belt. At picking zone, operator will scan a barcode that is on a picking container which represents the customer order. Barcode scanner is integrated with pick to light technology.

As operator scans the barcode of picking container, it launches the order sequence in line of racks at picking zone and light gets on at required product location and it also displays number of items to be picked. Once the pick location is illuminated, the operator will select the item for the order with quantities displayed, and put the product in container. After picking, operator hit the confirm button. As operator hit confirm button, light at picking location turns off.

When all the picking is done, no further lights get illuminated. Operator then close the container and continue the same process for next order. With pick to light system, we can track all real time information of picking and it is one of the best advantage of this system.


Real-time feedback on picking and the productivity of the operator.

Do not require any language requirements as only numbers are displayed.

System is simple and can be integrated with a company’s existing warehouse systems.


No requirement of any command: As it shows the quantity of product on display, there is no requirement of any repetition of command.

Increased Productivity: with pick to light technology, there are 450 picks per hour performed by each operator which increases productivity.

Saves time for searching location: as light illuminates at particular pick location, it saves time for searching location.
