Pick-to-Light System & Hardware for Warehouse Picking
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 barcode 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
- ●barcode scanners for combined scan-and-light execution
- ●Cloud dashboard for centralized monitoring and battery management
What's in a Pick-to-Light System
Three layers work together: wireless displays on the floor, a router for coverage, and a server that connects to your software — running in the cloud or on-site.
IoT Cloud Display Devices
- ●Battery-powered displays guide workers at shelves, carts, bins, workstations, and put-wall locations
- ●Show SKU, quantity, color, arrow direction, zone, order, tote, or operator instructions
- ●Mount in seconds with built-in magnets — no shelf wiring, and in most cases no mounting hardware
Turbo II Router
- ●Connects every Voodoo device back to the server over WiFi or POE
- ●Up to ~300 devices per router with 75–100 ft of range
- ●Add routers to blanket a facility of any size with reliable coverage
Voodoo Server — Cloud or On-site
- ●Runs in the cloud or on-site on your LAN — whichever your IT team prefers
- ●Receives pick tasks from your WMS, ERP, or MES, or a custom application
- ●Every button press or barcode scan flows back to the host system in real time
Many operations run the same wireless displays on mobile carts to build pick-to-light carts, pair them with RF scanners for closed-loop confirmation, or model device counts and rollout phases with our pick-to-light system cost guide.
Related Workflows
Pick-to-light is one workflow in the Voodoo platform. The same wireless displays also power put-to-light, put walls, pick-to-cart, pack-to-light, and kitting & sequencing. Browse the full set on Use Cases.
Purpose-Built for the Warehouse Floor
Voodoo's hardware is designed for demanding warehouse environments. Battery-powered display devices mount anywhere with no wiring, while the Turbo II Router provides reliable wireless coverage across your facility.
IoT Cloud Display Device
Try the display for yourself — set the text lines, quantity, arrow, barcode, and LED color in the live simulator and see exactly what workers see on the shelf.
