Pick-to-light at mid-market prices — why DIY install works

The quote that started this

A mid-market 3PL in Texas — six clients, 90,000 square feet, 18 pickers per shift — got a pick-to-light quote last spring. The scope was a single 24-light zone in a kitting area running 30% pick errors during peak. The enterprise vendor came back with $187,000 plus VAT and a 22-week timeline. Hardware was about a third of the number. Project management, controls engineering, integration scoping, on-site labour, and "system commissioning" made up the rest.

The operator forwarded us the quote with one line attached: "This can't be right."

It wasn't right — at least, not for them. It was right for the customer that vendor actually sells to: a Tier 1 retailer with a procurement department that requires a single throat to choke and a multi-year service contract attached. It was not right for a mid-market 3PL with a competent maintenance lead and one zone of 24 lights.

We sold them the same Banner Engineering hardware through the same distribution channel for around $14,000, with a DIY install guide. They installed it themselves in nine days. Pick errors in that zone dropped to under 1.5% inside two weeks. Here's how that worked.

Enterprise pick-to-light pricing isn't a hardware premium. It's a risk-transfer premium. Mid-market 3PLs don't need the risk transfer, because they already employ the person doing the work.

What an enterprise vendor is actually selling you

When a vendor quotes $187k for a 24-light zone, they're bundling several things into a single line item:

• The hardware itself. Banner Engineering pick lights, the Warehouse Bridge controller, the Banner gateway, industrial cabling, power supply. Real component cost in volume: under $15k for this scope.
• Controls engineering. A licensed controls engineer to spec the panel and draw the schematic. Useful at greenfield scale, mostly redundant for 24 lights in an existing aisle.
• Project management. A PM to run schedule, trades, and change orders.
• On-site labour. A union electrician crew at enterprise rates, with travel and per diem.
• Commissioning and acceptance testing. A two-week structured test plan with documented acceptance criteria.
• Service contract. Often a five-year SLA bundled into year-one pricing.
• Risk transfer. The unspoken bulk of the price. The vendor takes on liability for the project finishing, the system working, and the warehouse being operational. They price that risk into every line item.

For a Tier 1 retailer running a $400m annual fulfilment programme, every one of those line items is justified — they're buying certainty and they have the budget for it. For a mid-market 3PL with one zone, most are pure overhead. You don't need controls engineering: the components are standard. You don't need a project manager: the project is one person for nine days. You don't need union labour: your maintenance lead already knows how to hang things, run conduit, and torque a wrench.

What you need is the hardware, a wiring diagram, an integration script, and someone on the phone if you hit a snag. That's what we sell.

Why DIY install actually works

DIY install works at mid-market scale because the work isn't specialised — it just looks specialised in the brochure. Hanging a pick-to-light module is the same physical job as hanging a fluorescent fixture. Running low-voltage cable through cable tray is the same job as running data cable. Terminating an industrial quick-connect is a handful of pins, colour-coded, with the documentation telling you which goes where.

If you can hang a shelf and torque a wrench, you can install pick-to-light. The reason this comes as a surprise is that the enterprise industry has spent twenty years pretending otherwise.

Banner Engineering — the largest supplier of pick-to-light components in North America — sells most of its volume through distributors to OEMs, not to end users. Those OEMs hire engineers to specify the systems. The engineers aren't magicians; they're reading the same public datasheets we read. As a 3PL operator you never see the datasheets — you see a vendor pitch that wraps the hardware in services. We unwrap it.

The actual install for a 24-light zone

Here's the install flow we ship. It's the same flow we used in Texas. We're being specific because the specificity is the point — when the enterprise vendor tells you the install requires controls engineering, what they mean is, "we don't want you to know how simple this actually is."

Component list, 24-light zone:

• 24 × Banner Engineering pick lights (industrial-grade, multi-colour indication, IP67-rated for warehouse temperatures and dust)
• 1 × Warehouse Bridge controller (this is the brain — handles the light addressing and the integration with your WMS)
• 1 × Banner gateway (the floor-side unit that the controller drives, sitting in the aisle on industrial power)
• 1 × industrial-grade 24V DC power supply (sized for the light count, with about 25% headroom)
• Industrial quick-connect cordsets for each light (we spec 2m as standard; longer for end-of-aisle units)
• Drop cable from the gateway to the first light in the chain
• Mounting hardware — we ship a magnetic mount that snaps to standard rack uprights and a screw-mount alternative if your racks are non-magnetic
• DIN-rail panel enclosure for the controller and power supply
• A laminated A4 install guide and a single-page wiring diagram

That whole bill of materials lands around $14k for a 24-light zone, shipped on one pallet, with everything labelled by position so you can lay it out before you start.

Install steps, in order:

1. Mount the controller panel. A 200mm × 300mm enclosure that mounts to a wall or a rack upright near the zone. Pre-populated — the Warehouse Bridge controller and power supply already on DIN rail, terminal block wired. You're hanging a box. 45 minutes.
2. Wire the power feed. A 110V AC drop terminated to the power supply input. This is the only step where local code matters. In most US warehouses it's within facilities maintenance scope; in the UK and most of Europe a competent-person sign-off is sufficient. The install guide tells you which.
3. Hang the lights. Each Banner pick light clips into magnetic or screw mounts, both shipped pre-positioned and labelled. Lights mount at the bin or shelf face the picker looks at. For 24 lights in a typical pick aisle: two people, four hours.
4. Daisy-chain the cordsets. Each light has two industrial quick-connect ports — one in, one out. Drop into light 1's input, light 1's output into light 2's input, and continue. Connectors are quarter-turn, hand-tight, no tools.
5. Power on and address. The controller powers up, scans the chain, and assigns sequential addresses. Walk the aisle with a tablet, tap each light on the controller's web UI, confirm physical position matches logical address. About 20 minutes.
6. Integrate with the WMS. We ship the connector pre-configured for Camelot. Other WMS via CSV/API on request; native integrations on the roadmap. If you're on something we haven't seen, we publish the API contract or build the connector inside a week.
7. Acceptance test. Run 50 picks. Verify the right light fires in sequence, the cancel-press works, the multi-pick consolidation works. Half a shift of structured testing.

That's the install. Nine days end-to-end in Texas, including a two-day pause while they re-ran one cable that they'd routed across a forklift aisle. Nine days, one maintenance lead, one IT lead on the WMS bit, roughly $14k in components.

What you're trusting your maintenance lead to do

We have to be honest about what we're handing over. Your maintenance lead is responsible for hanging the hardware securely, running low-voltage cable in your existing tray, terminating industrial quick-connect cordsets (hand-tight, no torque spec to miss), and powering the panel from a 110V drop. The first three they do every week. The fourth is the only step where local code matters — the install guide tells them whether they need a licensed sign-off for their jurisdiction.

What we did NOT ask them to do: specify the components, design the panel, write the controller firmware, or write the WMS integration. That's the work that needed expertise, and we did it before the pallet shipped. The work we left is the work your facilities team does every week. That's the entire reason DIY install works.

When DIY install is the wrong answer

DIY install isn't the right answer for every operation. If you're running a Tier 1 retailer programme with a procurement requirement for a single integrator and a five-year SLA, buy the enterprise system. The risk transfer is what you're actually buying, and our model isn't built for that.

DIY install is the right answer when you have a competent maintenance lead and IT lead, your zones are bounded (12 to 80 lights at a time, not 4,000 across a continent), you can absorb a shift's slip if the install hits a snag, and you want the hardware to belong to you rather than be wrapped in a service contract that escalates every year. That describes most mid-market 3PLs we work with — and the enterprise vendors don't sell to that reality because the deal sizes are too small for their cost structure.

What to do next

If you're looking at a pick-to-light quote right now with six figures on the cover, pull out the hardware line and call us. We'll quote the same Banner Engineering hardware at component prices, ship it to your dock, and walk you through the install on a call. The full hardware page is at our pick-to-light hardware, and you can take the 3PL Operating Scorecard to check whether Light It is actually your next step — or whether you'd get more from See It or Map It first.

We're not going to put engineers on your floor. You know your warehouse better than any consultant we could send. We'll ship the parts, the diagram, and the integration, and we'll be on the phone when you need us. That's the deal.
