Which light-directed fulfillment method fits your process.
Pick-to-light warehouse picking system in use

Put-to-Light and Pick-to-Light are both light-directed fulfillment technologies that improve picking speed and accuracy, but they're optimized for different order profiles.

What is Pick-to-Light?

Pick-to-Light guides an operator to the correct pick location using illuminated indicators, confirming each pick in real time.

What is Put-to-Light?

Put-to-Light works in reverse — an operator picks a batch of mixed items, then light indicators guide them to sort and place each item into the correct order tote or slot.

The short answer

Pick-to-Light suits precise single-order picking, while Put-to-Light suits high-volume batch fulfillment where many orders are consolidated at once — many facilities combine both across different zones.

FAQ

Frequently Asked Questions

Can both systems be used in the same facility?

Yes — many fulfillment centers use Pick-to-Light for slower-moving SKUs and Put-to-Light for high-velocity batch orders.

Do these systems require a WMS?

Yes — both integrate with a WMS or order management system to know which lights to trigger for each order.

Is Put-to-Light more expensive to install than Pick-to-Light?

Not usually — cost tracks the number of light positions, not the method. Pick-to-Light needs a display at every pick face you want covered, so a high-SKU zone can run into more positions. Put-to-Light needs one position per order slot on the put location. Cabling, controllers, and WMS integration effort are broadly comparable between the two.
