Pick-to-light and put-to-light
Lights and displays at each location show where to pick and how many; press to confirm. Low investment, fast to install, an entry step for fast-moving small items.
Lights and displays at each location show where to pick and how many; press to confirm. Low investment, fast to install, an entry step for fast-moving small items.
With pick-to-light, every location has a light with a numeric display and confirm button. When the picker scans an order, the locations to pick light up and show the quantity; the picker takes the items, presses to confirm and moves to the next light, without reading a pick list. Put-to-light works the other way round: a batch is picked first, then each item scanned lights the order slot on a wall or rack, the item goes in and the light is pressed. Both can be used on their own or with goods-to-person stations and put walls.
Typical uses
- Fast-moving small items in e-commerce, pharmaceuticals and spare parts
- Store allocation and order consolidation
- Put indication at goods-to-person stations
- Returns and small-order consolidation
How to choose
- SKU count and daily order lines: fast movers fit best
- Batch-pick-then-put or pick by order
- Rack type: flow rack, shelving or put wall
- How it connects to the WMS
When it is not the right choice
- Huge numbers of SKUs that are rarely picked: a light on every location does not pay; use handhelds or goods-to-person
- Large items and full-case picking: light guidance adds little; compare with RF handhelds and voice picking per project
