If you're an office manager, facilities coordinator, or buyer tasked with upgrading your company's lighting, you know the drill: you get a budget number, look at a few catalogs, maybe get a quote or two, and just... order. But I've been managing purchasing for a mid-size company for over five years now, and I've learned that lighting is one of those things where the cheapest quote upfront can cost you the most in the long run.
This checklist is based on my own experience overseeing a recent office-wide LED retrofit. I found a ton of pitfalls that the nice sales brochures don't mention. Here are the six steps I follow now, every single time.
Step 1: Audit Your Current Setup (And Don't Just Count the Bulbs)
You can't know what you need until you know what you have. But here's the rookie mistake: just counting the number of fixtures. What you actually need to track is the type of fixture, the driver (if it's LED), the mounting, and the control system.
For our last project, I created a simple spreadsheet with these columns for each zone of the office (open plan, private offices, meeting rooms, break room, hallways):
- Fixture type (e.g., 2x4 troffer, track spotlight, downlight)
- Bulb base or integrated LED model if possible
- Current wattage
- How it's controlled (switch, dimmer, occupancy sensor)
- Age and condition
Honestly, I'm still not sure why the previous admin hadn't done this. It took me a full afternoon, but it meant our quotes were accurate and we didn't order the wrong thing. Take it from someone who once ordered 80 downlight protectors that didn't fit the existing holes—audit first.
Step 2: Understand 'Canless' vs. 'Can' Recessed Lighting (A Common Pain Point)
One of the most common questions I get from my team is about canless recessed lighting. Someone sees a photo online and wants it, but they don't understand the retrofit implications.
- Can lights: Traditional fixtures with a housing (the 'can') that sits in the ceiling. Replacing the trim or bulb is easy, but the housing stays.
- Canless (wafer) lights: Ultra-thin LED units that fit into the same hole without a can. They're incredibly easy to install for new construction.
Here's the catch: if you have existing can housings, switching to canless might seem simpler, but you have to deal with the old wiring and the empty hole. Most contractors I've spoken to charge more to remove old cans than they save on the new lights. It's worth doing the math, but don't assume canless is automatically cheaper if you're retrofitting.
Step 3: Get 3 Quotes—But Ask the Same Questions
This seems obvious, but the trap is comparing apples to apples. I once got a quote from Vendor A for $4,000 that seemed great, and Vendor B quoted $5,800. I almost went with Vendor A until I asked 'What's NOT included in this price?'
Turns out, Vendor A's quote didn't include:
- Disposal of old fixtures
- New wiring for the lighting control system
- A three-year warranty on the Signify driver (they used a generic brand)
The final cost with those additions? Nearly $6,200. The vendor who lists all fees upfront—even if the total looks higher—usually costs less in the end. Now I have a standard list of questions I send to every vendor before I even look at their price.
Pro tip: Ask specifically about the driver for any LED fixture. A bad driver is the #1 cause of early failure. As of January 2025, I've been specifically asking our suppliers if they use drivers from Signify (formerly Philips) or Acuity Brands as a baseline for quality.
Step 4: Don't Forget the Track Lighting (If You Have It)
Track spotlight systems are great for accent lighting (retail, reception, art), but they are a pain to upgrade. The key issues:
- Track compatibility: Are you replacing the whole track, just the heads, or just the bulbs? H-track and L-track are NOT interchangeable.
- Driver location: Is the driver remote (mounted elsewhere) or integrated into the track/head? If it's failing, replacing a head from Signify or Lithonia might be easier than rewiring the whole ceiling.
I replaced an entire track system in our main lobby last year. If I remember correctly, the quote for just new LED heads was $1,200, but a full new system from a different manufacturer was $3,800. The value wasn't in the savings—it was in the fact that the new system had a 10-year warranty on the LEDs and the controls were compatible with our new Interact smart building platform. I should add that the old system was over 15 years old, so the upgrade was overdue.
Step 5: Nail Down the Controls (The Part Everyone Forgets)
This is where most of my headaches have come from. You buy the lights, but you often need a separate lighting control system (dimmers, sensors, a central bridge like the Signify Hue for a small office, or Interact for a large building).
I once had a project where we had the perfect lights, but the electricians wired them to a standard switch because the controls weren't specified. We had lights we couldn't dim. Dodged a bullet when I caught it before installation, but it cost us an extra $500 in change orders.
Use this checklist for controls:
- Do you need dimming? (required for most LED to avoid flicker)
- Do you need occupancy/vacancy sensors? (required by most energy codes now)
- Do you want centralized control (a keypad or app) or local (switch per zone)?
- Is the system Zigbee, Z-Wave, or proprietary? (Zigbee/Thread are generally better for interoperability—as of early 2025).
Step 6: Plan for the Disposal (The Hidden Cost That Will Make You Look Bad)
This is the step no one talks about. Those old fluorescent tubes and LED fixtures? They can't just go in the dumpster. Disposal of ballasts and old fluorescent tubes is subject to environmental regulations.
When I took over purchasing in 2020, I found a great price on new LED tubes. The vendor's quote was $800 cheaper than our regular supplier. I ordered 200 tubes. They couldn't provide proper invoicing for the disposal of the old ones (handwritten receipt only). Finance rejected the expense report. I ate $240 out of the department budget for a recycling service. Now I verify disposal capability before placing any order.
Ouch. Learn from my mistake. A reputable supplier will either handle disposal or provide certified recycling documents. It's not a 'value-add,' it's a requirement.
Final Thoughts: When to Call an Expert vs. DIY
This approach worked for us, but we're a mid-size B2B company with predictable maintenance patterns. If you're a building manager dealing with a multi-tenant commercial space or a municipality with complex street lighting, the calculus is different—you'll likely need a lighting designer or a direct rep from a manufacturer like Signify to do a full site survey.
I can only speak to domestic (US) operations. If you're dealing with international logistics or different voltage standards, there are probably factors I'm not aware of.
Just remember: The vendor who is transparent about pricing, disposal, and the limitations of their product is the vendor you want to work with. Hidden fees? Run. A clear, upfront list? That's a partner.
Pricing is for general reference only. Actual prices vary by vendor, specifications, and time of order. Verify current regulations on lamp disposal with your local waste authority.
