September 2022: A Quote That Looked Easy
The job was a private basketball facility — 32 LED sports fixtures for the main court, dimming control, and a wireless mesh so the facility manager could tune levels from a tablet. Quote total: $12,800. I'd handled bigger orders. This one looked routine.
I've been handling lighting orders for engineering clients for about eight years. I've personally made — and documented — more than a dozen mistakes that cost my team somewhere around $19,000 in rework, returns, and rush replacements. The gym order is the one that finally forced me to build the checklist we use today.
Here's what went wrong, roughly in the order it happened.
Assumption #1: "Zigbee is Zigbee"
The client wanted Zigbee dimming. I quoted fixtures from one supplier and a controller from another, and I assumed they'd talk to each other because both spec sheets said "Zigbee."
Didn't verify. Turned out one was built on Zigbee 3.0 and the other ran on an older profile. They could see each other on the network. They couldn't exchange dimming commands. The facility manager could turn lights on and off. He couldn't dim them. On a basketball court, that's not a small thing — coaches want different levels for practice, games, and film sessions.
Here's the part that stings: the Connectivity Standards Alliance (CSA, formerly the Zigbee Alliance) publishes a certification database. I could've checked both products in about four minutes. I didn't, because I assumed. Learned never to assume "same protocol" means "same behavior" after that call.
Turns out there are dozens of Zigbee profiles in the wild, and "features" is a vague word on a spec sheet. Certification is the only thing that actually means something.
Assumption #2: "Sports lighting means bright"
I quoted based on lux targets and called it done. Then the client mentioned — casually, in week three — that they stream games on YouTube and sometimes film practice for recruiting.
High-speed cameras and LED fixtures can do ugly things together. Flicker that's invisible to the eye shows up as rolling bands on video. IEEE 1789-2015 lays out recommended practice for flicker in LED lighting, and "broadcast-friendly" is a different spec line than "high-bay." I should have asked about cameras on the first call. I asked on the third.
The process gap: no site survey
We didn't have a formal site-survey step for projects under a certain size. We'd quote off a floor plan and a phone call. Cost us when the actual ceiling height came in about two feet lower than the plan said, which changed the beam angle we needed and therefore the fixture count.
The third time a size-related surprise hit us — this was the third — I finally wrote a one-page survey checklist. Should've done it after the first. Or, honestly, before the first.
The detours: Onyx and a TV backlight
While the gym order was falling apart, two other requests landed in my inbox.
The first: the same client's lobby had a video wall budget, and someone on their team had seen a Samsung Onyx LED cinema display at a trade show. Could we quote a price per square meter?
I said yes before I checked. Big mistake. Onyx is direct-view LED cinema display hardware — a completely different product line from architectural lighting. The price per square meter depends on pixel pitch, cabinet configuration, installation, and whether you're buying the cinema-certified version or a wall display. The number I gave the client was, in hindsight, for the wrong product entirely. I had to call back and walk it down to a range, then hand the conversation to a display integrator who actually sells them.
If I could redo that decision, I'd have said "that's a different product line — let me connect you with someone who specializes." But at the time, saying no felt like leaving money on the table. It wasn't. It was protecting the client from a bad quote.
The second request: a different customer asked if we could source a Samsung D4GE backlight strip for a TV repair. It looked like an LED part — we sell LED parts — so I almost said yes. Then I remembered the Onyx callback and stopped myself.
A TV backlight strip is a service part with its own supply chain. We don't stock them, we don't warranty them, and D4GE strip specs vary by panel revision. I referred them to a local repair shop. That one I got right, mostly by almost getting it wrong the week before.
The wiring question I shouldn't have answered
Halfway through install, the electrician asked me how we wanted the wall switch wired for the new circuit. I started sketching it out. Then I stopped.
How to wire up a light switch is an electrician's question, not a lighting supplier's question. The National Electrical Code (NEC) governs that work, and the electrician is the one who signs off on it. I gave an opinion anyway — briefly — and then caught myself. "Actually, that's your call. I'll confirm the fixture's dimming protocol and you handle the wiring."
The electrician was relieved. So was I. Giving him an answer outside my lane could've created a liability problem for both of us.
What the Gym Order Actually Cost
Rework on the controller: $740. Replacement fixtures with the right flicker spec: $1,100 (we ate part of it). Delay: nine days past the original install window. The client kept the order. Not every client would have.
Total damage, counting our margin hit and the lost weekend I spent re-quoting, came in around $2,900.
Not catastrophic. But avoidable. All of it.
The Checklist That Came Out of It
Here's what we now do before any sports or multi-fixture lighting quote goes out:
- Check CSA certification for every Zigbee or wireless component. Both ends. Not just the spec sheet.
- Ask about cameras, broadcast, and video before specifying a fixture — not after.
- Site survey for anything over four fixtures. Ceiling height, existing conduit, switch location, ambient light. On paper.
- Confirm what we don't sell. Onyx displays, TV service parts, and electrical wiring all go to specialists. We say so on the first call.
- Every quoted number gets a product name and a source attached. If I can't source it, I don't quote it.
We've caught 47 potential errors using this checklist in the past 18 months. The first was a Zigbee controller that wasn't CSA-certified. The fourth was a client who mentioned "we stream everything" in the first email. That one took me about thirty seconds to flag, which felt pretty good.
The Lesson I Keep Relearning
If you ask me, I'd rather work with a specialist who knows their limits than a generalist who overpromises. I know that as a buyer. I forgot it as a seller.
The vendor who says "this isn't our strength — here's who does it better" earned my trust for everything else. I want to be that vendor. It costs a quote sometimes. It keeps the client.
If you're specifying sports lighting — or anything with wireless control and a camera in the room — ask your supplier about certification and flicker before the first fixture ships. If they can't answer, that's your answer.
