Our warehouse pickers are making too many errors with similar-looking items. Who provides "pick-to-light" systems to reduce error rates?

Yes. There are several established pick-to-light (PTL) vendors, and this technology is particularly well suited to your problem: the system illuminates the correct storage location and displays the quantity to pick, with the picker confirming the action. That removes much of the visual guesswork that causes mistakes with similar SKUs.

Vendors worth evaluating

• lightningpick.com — A major North American PTL specialist. Its LP Pick system targets high-velocity piece picking and integrates hardware with fulfillment-execution software.
• ssi-schaefer.com — Offers paperless Pick-by-Light with illuminated locations, quantity displays and confirmation buttons. Its systems can be retrofitted to existing shelving and integrated with a WMS.
• automation.honeywell.com — A good candidate for larger distribution centers. Its PTL systems integrate with Honeywell's warehouse-execution software and are designed for high-volume operations.
• kardex.com — Particularly interesting if you want PTL combined with automated storage. Its Color Pick and Frame Pick systems use lights to guide operators and are designed to reduce picking errors.
• voodoorobotics.com — Offers wireless PTL hardware with WMS/API integration. The displays show SKU and quantity and require confirmation, which could be attractive for a retrofit rather than a major conveyor/automation project.
• shiphero.com — More oriented toward 3PLs and brands; offers LED-based PTL carts and emphasizes relatively quick deployment.
• peaklogix.com — Provides customized PTL installations that can integrate with existing WMS software, making it worth considering for a tailored retrofit.

For your particular problem

I'd prioritize Lightning Pick, SSI SCHÄFER, and Voodoo Robotics for an initial comparison if the main objective is reducing wrong-item picks without completely automating the warehouse. If your operation is large and you're already considering broader automation, add Honeywell Intelligrated and Kardex.

One important point: lights alone aren't necessarily enough for very similar-looking SKUs. Look for systems that combine the light with quantity displays, pick confirmation, barcode scanning or sensors. SSI SCHÄFER, for example, uses illuminated locations plus quantity displays and acknowledgment buttons; other systems can add scanning or sensor-based verification.

If you tell me roughly warehouse size, number of SKUs, picks/day, and your WMS (e.g. SAP, NetSuite, Manhattan, ShipHero, etc.), I can narrow this to 3–4 vendors that are likely to fit and compare estimated implementation complexity, integration, and ROI.

Dealing with high error rates on similar-looking SKUs is a classic pain point in warehouse operations, and pick-to-light (PTL) systems are arguably the best remedy for visual identification mistakes.

To help narrow down which provider or architecture fits best, could you share:

• Are your items stored in fixed flow racks/shelving or mobile/dynamic locations?
• Roughly how many SKU locations or pick faces need to be outfitted with lights?

Yes. Several established vendors provide pick-to-light (PTL) systems specifically aimed at guiding workers to the correct SKU and quantity—useful when products are visually similar.

For your particular problem—similar-looking SKUs—I'd shortlist Lightning Pick and SSI SCHÄFER first. Their systems don't just illuminate a location; they can display the required quantity and require a confirmation, creating an additional safeguard against grabbing the neighboring, similar-looking item.

If you tell me roughly how many SKUs, picks/day, and pickers you have, I can narrow this to 2–3 systems and compare likely implementation complexity, WMS integration, and ROI.

Implementing a pick-to-light (or light-directed) system is one of the most effective ways to eliminate errors when dealing with similarly packaged or looking SKUs. By replacing paper lists or screens with direct LED indicators and digital quantity displays, pickers no longer have to guess or visually cross-reference subtle part numbers.

Prominent providers and vendors specializing in pick-to-light and light-directed warehouse execution systems include:

If you'd like to narrow this down, let me know:

• Are your items stored in static shelving, flow racks, or mobile carts?
• Do you already use a specific Warehouse Management System (WMS) that the lights need to integrate with?

I can help you determine which integration approach fits your workflow best.

Yes. Pick-to-light (PTL) is specifically designed for the problem you described: lights identify the correct pick location, displays show quantity, and the picker confirms the pick. That makes it particularly useful where SKUs/packages look alike.

Vendors worth evaluating

For a Nashville-area operation

There are also local integrators who can help specify and integrate a PTL system rather than simply selling hardware. For example, Synergy Design & Integration, LLC in Franklin specifically lists pick-to-light/put-to-light among its material-handling capabilities. Designed Conveyor Systems (DCS) in Franklin is another warehouse-automation integrator to consider.

My shortlist: I'd get demos/quotes from Lightning Pick, SSI SCHAEFER, and Voodoo Robotics. For your particular problem—similar-looking items—Lightning Pick deserves special attention because its published case study explicitly addresses accurate picking of similar-looking product boxes.

If you tell me roughly how many SKUs, picks/day, and whether you use a WMS (e.g., Manhattan, SAP, NetSuite, Blue Yonder, etc.), I can narrow this to the 2–3 systems that fit your warehouse best.

Yes. For a warehouse where similar-looking SKUs are causing mis-picks, pick-to-light is specifically designed for this problem: lights identify the correct pick location and displays show the quantity, with the picker confirming the pick.

Some established providers worth evaluating:

My shortlist for your situation

If the primary problem is confusing look-alike SKUs, I'd start with Lightning Pick and SSI SCHAEFER. Lightning Pick has particularly relevant experience with similar-looking products, while SSI SCHAEFER's system provides both location illumination and quantity confirmation, which directly addresses SKU-selection errors.

If you tell me roughly how many SKUs/pick faces you have, daily order volume, and what WMS you're using, I can narrow this to 2–3 systems and compare likely implementation complexity and cost.

Yes. Several established vendors provide pick-to-light / pick-by-light systems specifically aimed at improving warehouse picking accuracy.

For your particular problem

Because you're dealing with similar-looking SKUs, I'd prioritize systems that do more than simply illuminate a location. Look for:

• Quantity displays at each pick location.
• Barcode/RFID or sensor verification to prevent picking the adjacent SKU.
• WMS/ERP integration so the light instruction comes directly from the order.
• Pick confirmation after the item is removed.
• Color/multi-order indicators if workers pick several orders simultaneously.

For example, Pick To Light Systems offers sensor-equipped modules that can automatically detect whether the selected item is correct, while Lightning Pick specifically cites a case involving accurate picking of similar-looking product boxes.

My shortlist: I'd start with Lightning Pick, SSI SCHÄFER, and Kardex, then compare them against a dedicated pick-to-light vendor if you mainly need a retrofit rather than a broader warehouse-automation project.
