    Pick-to-Light System & Hardware for Warehouse Picking

    Wireless pick-to-light systems — also called pick-by-light, pick2light or light-directed picking — that eliminate search time, reduce errors, and confirm every action in real time.

    New to light-directed picking? Start with What Is Pick-to-Light? — how it works, the types, and what drives the cost.

    How Pick-to-Light Works

    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.

    📡
    1

    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
    System Architecture

    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 PoE Ethernet (preferred) or WiFi
    • ●Up to 350 devices per router (plan ~100 for best latency), 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.

    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.

    Hardware

    Purpose-Built for the Warehouse Floor

    Voodoo's pick-to-light hardware is designed for demanding warehouse environments. Each pick-to-light display module is a battery-powered device that mounts anywhere with no wiring, while the Turbo II Router provides reliable wireless coverage across your facility. Pilots and systems of up to 50 devices run on Voodoo's cloud server, so there is nothing to install; larger systems get their own Voodoo server, in the cloud or on-site.

    Pick a time that suits you. We'll look at your pick zones, talk through arrows and device counts, and tell you if a Starter Kit makes sense.

    What we'll cover
    • Your pick zones, SKU mix and order profile
    • The arrows ratio that fits your shelving — 1:1, 1:4 or 1:8
    • Whether a Starter Kit pilot or a full quote is the right next step
    • How the devices talk to your WMS, ERP or Odoo
