Thursday, 3:42 PM
I'm an order coordinator at a design lighting distribution company. Nine years, 400-plus rush orders, everything from same-day small jobs to installs north of $15,000. So when the call came in at 3:42 on a Thursday afternoon in October 2024 and the first thing I heard was "four days," I didn't panic. I heard, "start confirming what's actually possible."
The client was a production company I'd worked with twice before. No small talk — she gave me the deadline first, then the list. Twelve Flos Oblique table lamps for the guest tables. Eight Flos lighting floor lamps for the lounge. Thirty downlight fixture units on an existing truss. And one final moment: a speaker doing a five-minute monologue, spotlight acting as the only light source on a small raised platform.
That last part mattered more than it sounded. The spotlight was going to be a surface-mounted unit with a snoot and a cutoff grid, and the beam had to stop at the performer's shoulder line without spilling onto the tables. That detail nearly became the biggest problem in the whole project. I didn't know that yet.
Normal lead time on Flos orders: three to four weeks for custom, one to two for standard stock. We had four days.
72 Hours, Broken Down
Step one: check stock.
Flos Oblique table lamps — found twelve. A regional dealer had a canceled order sitting in their warehouse, matte black, original packaging. That call took twenty minutes and more than a little luck.
Flos lighting floor lamps — eight units with dimmable drivers, ready to go. The downlight fixture order was easier still: standard spec, local stock, easy enough to pair with a cutoff grid and trim.
By that point, the four-day window looked open.
One thing I should mention here. The old "local is always faster" rule comes from an era when inventory lived in separate regional warehouses. Today, assuming the dealer's stock data is accurate, a rush order from a different region can hit the venue faster than a local warehouse manager who takes two days to confirm at SKU level.
Products were in motion. Then the real problem showed up.
The Zigbee Problem
The venue was a converted warehouse — exposed brick, high ceilings, the kind of space that makes downlight placement interesting in the wrong way. But the bigger issue was that the building already ran a Zigbee mesh: HVAC sensors, motorized shades, and a building management dashboard the owner was genuinely proud of. My client had already told him the new lighting would "plug right in."
That's where I needed to understand how Zigbee works — or more precisely, where I needed to confirm what we couldn't do.
To be clear: we install lighting. Wiring, circuits, dimming, track, all of it. But Zigbee mesh commissioning — coordinators, router nodes, firmware version matching, gateway handoff — is not our strength.
We learned that the hard way in 2022. I thought, "How hard can Zigbee be? It's basically Wi-Fi." It isn't. The coordinator kept dropping, three fixtures had firmware that didn't match the gateway, and on rehearsal day the entire left side of the room was flickering. I brought in an outside engineer at the last minute, paid $1,400 in emergency fees, and apologized to the client. Not because the job was impossible — because I'd taken on a piece of work that wasn't ours to take.
I wasn't going to repeat that.
When I Said "We Don't Do That"
What I told the client was roughly this: "We'll handle the fixtures and the installation. The Zigbee integration goes to a specialist. That cost goes into the total."
Her first question was whether that meant we were padding the invoice. I said no — it meant we weren't going to pretend. Doing it ourselves would have cost more, not less.
I called a commissioning engineer I've worked with for years. He handles Casambi, Zigbee, and DALI — doesn't sell product, just commissions and tests. He spent an hour on the phone confirming gateway compatibility, then ten minutes walking me through how Zigbee mesh actually routes. Every product spec mentions the coordinator builds the network, and per the Connectivity Standards Alliance (csa-iot.org), Zigbee runs on 2.4 GHz in a mesh topology where every powered device can act as a router node. The distinction that mattered to me: distance and walls affect link quality rather than "signal present or not."
That's a difference I couldn't have learned in a month of trial and error. For him it was Tuesday.
He came in the day before install, ran a preset, and left a four-hour commissioning window. Everything connected — twelve Flos Oblique table lamps, eight floor lamps, thirty downlight fixture heads — before the Friday afternoon rehearsal.
There's a process point here. After the 2022 mess, I built a two-column checklist: left side, "we can do this"; right side, "this needs an outside expert." It sounds basic. But that checklist is the reason the Zigbee work never ended up in the wrong column this time.
Friday Morning, Walkthrough
Friday afternoon, rehearsal. The twelve Flos Oblique table lamps threw a soft pool of light across the long tables — no glare, nothing harsh, exactly the quality the spec called for. The eight floor lamps cross-lit the lounge and pulled the brick wall out of the background. The downlight fixture run on the truss held the ambient level steady. The spotlight acting moment got its own circuit, and when the performer stepped up, the beam cut right at the shoulder. The director said one word: "that's it."
The venue manager didn't call us once that night.
What I keep coming back to is this: the project worked because of what we didn't do, not just what we did.
After nine years of rush work, I've become convinced of something. A supplier who says "that's not our strength, here's who does it better" is more reliable than a supplier who says they can do everything. Especially with a project like this — Flos product, fixture design, control systems, and an existing building network are four different jobs. The distributor is fast on delivery. The integrator is steady on protocol. Put them together, and you get a real rush solution.
If you're specifying Flos in a space that already has a control system, budget for commissioning separately. Not as insurance — because it's a different job. For the designer, the distributor, and the venue, that's the honest version.
