Pick to Light — Guide Every Pick, Confirm Every Action
Wireless pick-to-light systems — also called pick-by-light or light-directed picking — that eliminate search time, reduce errors, and confirm every action in real time.
Light Up. Pick. Confirm. Done.
A simple, guided workflow that turns every pick into a confirmed, error-free action — whether used standalone or alongside RF scanners.
Task Arrives
Your WMS sends a pick task through the REST API to the Voodoo server.
Device Lights Up
The display shows SKU, quantity, and instructions. The LED glows the assigned color.
Worker Picks
The operator goes to the lit location, reads the display, and picks the item.
Button Confirms
A button press confirms the pick and sends confirmation back to your system.
When to Use Pick to Light
- ●High-volume zone or batch picking with dozens to thousands of SKUs
- ●Fast onboarding — new hires need to pick accurately on day one
- ●Error-sensitive operations where mis-picks drive returns and chargebacks
- ●Stable pick faces where devices stay at fixed shelf or rack locations
- ●Multi-zone warehouses needing guided picks without conveyors
Why Wireless Pick-by-Light
- ●No conduit, no wiring, no electricians — deploy devices in minutes
- ●Battery-powered displays last years on standard AAA cells
- ●Reconfigure pick faces and zones without infrastructure changes
- ●Scale from 10 devices to 1,000+ with no architectural changes
- ●Wireless outperforms wired on cost, flexibility, and deployment speed
What It Integrates With
- ●Any WMS via standard REST API — no proprietary middleware
- ●SAP, Oracle, Manhattan, Blue Yonder, Körber, HighJump, and more
- ●ERP and MES systems for manufacturing pick-by-light workflows
- ●RF scanners for combined scan-and-light execution
- ●Cloud dashboard for centralized monitoring and battery management
Pick to Light vs. Other Workflows
Pick-to-light — also called pick-by-light or light-directed picking — is one of several workflows in the Voodoo platform. Here's how it fits relative to adjacent methods.
Pick to Light vs. Put to Light
Pick-to-light guides retrieval — the display lights up where items live on shelves. Put-to-light (sort-to-light) guides placement — operators sort pre-picked items into order locations. Many facilities use both: pick-to-light for gathering and put-to-light for sortation, running on the same hardware.
Pick to Light vs. Pick to Cart
Fixed pick-to-light mounts displays at shelf or rack positions — ideal for high-velocity zones with stable SKU layouts. Pick-to-cart (cart-based picking) puts displays on a mobile cart, making it better for dynamic layouts, cold storage, or operations without fixed infrastructure.
Pick to Light vs. Kitting & Sequencing
Standard pick-to-light executes one pick at a time from a picklist. Kitting and sequencing (light-directed assembly) enforces a strict build order — each bin lights in sequence, and the operator must confirm before the next step activates. Kitting adds sequence enforcement to the same hardware platform.
One System. Many Workflows.
The same devices and software platform support every warehouse workflow below. Deploy for one use case and expand to others without new infrastructure or retraining.
Zone Picking
Light guides workers to the exact shelf location within their assigned zone, eliminating search time and reducing travel distance.
Batch Picking
Pick multiple orders simultaneously with color-coded LED indicators assigning each order a unique color across devices.
Put-to-Light
After picking, sort items into outbound orders with light-guided put locations. Each display shows the destination and quantity.
Kitting & Assembly
Guide operators through multi-component assembly sequences with step-by-step visual instructions on each device display.
Reverse Logistics
Process returns efficiently with light-directed sorting into restock, repair, or disposal locations.
