I manage facilities procurement for a 300-person manufacturing operation—about $180,000 annually across maintenance, equipment, and lighting. When I took over in 2019, I assumed lighting was lighting. One brand, one vendor, one invoice. Clean and simple.
That assumption cost us roughly $4,200 in the first year: two incompatible product returns, one rush order we didn't need, and a restocking fee I'm still annoyed about. The problem wasn't the products. It was that I was treating three completely different purchasing decisions as if they were the same thing.
Here's the framework I've used since 2021. It's not elegant, but it's saved us money every quarter.
Three Lighting Scenarios (They Don't Share a Budget)
Before I request a single quote, I sort the purchase into one of these buckets:
- Scenario A: Replacing lamps or components inside an existing system (ballast compatibility matters more than anything else)
- Scenario B: Installing new fixtures or upgrading a space (you're buying a system, not a product)
- Scenario C: Specialty applications and maintenance (expertise beats unit price)
Each one gets a different spreadsheet. Mixing them up is how you end up paying $18 for a $6 part (this was back in 2022, and I'm still not over it).
Scenario A: Retrofitting Inside an Existing System
This is where GE lighting ballast compatibility becomes the entire conversation. We have about 1,200 linear fluorescent fixtures across our production floor and warehouse. In 2023, we started converting to LED tubes.
My first instinct was to buy the cheapest compatible tube and move on. That's the wrong way to think about it.
There are two ways to retrofit a fluorescent fixture with LED tubes:
Plug-and-play (ballast-compatible): The LED tube works with the existing ballast. Install is fast, and you don't need an electrician for most swaps. But here's the catch—the ballast doesn't last forever. When it fails, you're back to replacing both the ballast and the tube. Older ballasts weren't designed for LED loads either, which can shorten their life.
Direct wire (ballast bypass): The ballast comes out completely. The tube wires straight to line voltage. Yes, it costs more upfront—usually $15–$25 per fixture in labor (as of early 2025, depending on your market). But you've eliminated a failure point and a recurring maintenance cost.
When I ran the TCO numbers in 2023, direct wire came out about 12% cheaper over five years, mostly because we weren't paying electricians to swap ballasts above a 24-foot production line. That wasn't the answer I expected. It looked more expensive on the initial quote.
So glad I ran that calculation before ordering 200 plug-and-play tubes. Almost went with the lower invoice, which would have meant another retrofit three years later.
If you're staying with plug-and-play—and there are good reasons to, like limited labor availability or partial system replacements—check the manufacturer's compatibility chart first. Not just "does it work," but "which ballast models specifically." GE Lighting publishes this information, and so do most serious brands. A mismatch here is an expensive lesson in reading fine print.
The "always replace the whole fixture" thinking comes from an era when LED retrofits were unreliable and ballast compatibility was a mess. That's changed. For most standard linear fixtures, direct-wire retrofits are a solid middle path between doing nothing and rebuilding everything.
Scenario B: New Fixtures and Space Upgrades
This one bites differently. When you're installing new fixtures—say, GE under cabinet lighting 12-inch strips for a break room refresh, or wireless spotlights for a display area—you're not buying a lamp. You're buying a system, and systems lock you in.
Three things matter more than the unit price:
1. Standardization across locations. We have four buildings. If Building A gets 12-inch hardwired under cabinet fixtures and Building B gets wireless battery spotlights, my spare parts inventory doubles and my electricians have to remember two installation methods. Not a dealbreaker, but a hidden cost. I now track "unique SKUs per lighting project" as a line in my budget. Anything above three gets scrutiny.
2. Ecosystem compatibility. Smart lighting is the obvious example. GE Lighting's Cync ecosystem works well if you're already in it. But if you have existing Zigbee controls from another vendor, adding Cync devices means running two control systems or replacing what you have. Zigbee-certified devices usually interoperate better, but "usually" isn't "always" (i.e., check the actual device list, not the marketing page).
3. Maintenance access. Wireless spotlights sound great until the batteries need replacing in a 20-foot ceiling. Battery-powered fixtures cost $8–$15 per battery swap in labor (this was back in 2024, and it climbs with ceiling height). That $40 spotlight can cost $100 over three years. Hardwired is more expensive upfront, but the maintenance math flips fast.
This was true 10 years ago when smart lighting was fragmented and battery life was unreliable. Today, the options are better—but the tradeoffs still exist. Don't let a product demo convince you that "wireless" means "maintenance-free."
Scenario C: Specialty Lighting and Maintenance
This is the scenario where expertise matters more than unit price. Lighting sports facilities and outdoor flood lights are the two best examples I deal with.
Sports lighting isn't a commodity purchase. The photometric requirements alone—footcandles at the playing surface, uniformity ratios, glare control—mean you're buying engineering, not just fixtures. We looked at converting our outdoor field from metal halide to LED in 2022. The fixtures themselves were competitive, but the design work and installation labor were 40% of the project cost. And the "cheap" option from a general contractor would have required a redo when the light levels didn't meet league standards.
For sports lighting, get a photometric plan before you get a price. Any vendor who quotes without one is guessing, and you'll pay for their guess later.
Outdoor flood lights and maintenance are a different kind of decision. When our facilities team asked how to remove a flood light cover safely—we had 14 units on building exteriors—my first question was whether this was a maintenance task or an electrician task. The answer depends on the fixture: some covers pop off with a spring clip; others need the unit de-energized and disassembled. If your team isn't sure which type they're dealing with, that's a $75–$150 electrician call (as of early 2025, in our market). Cheaper than a fall or a shock.
For this scenario, I budget for service, not just product. That means design fees for sports lighting, service contracts for hard-to-reach fixtures, and a small contingency for "we didn't know what we didn't know."
How to Know Which Scenario You're In
Answer these three questions before you open a spreadsheet:
- Are you keeping the existing infrastructure or replacing it? If you're keeping the fixture housing or wiring, you're in Scenario A. Compatibility and total cost of ownership matter more than unit price.
- Are you buying for one space or standardizing across multiple? One space might justify a specialized or wireless solution. Multiple spaces usually justify standardization, even if the per-unit price is higher.
- Does the project require design work or specialized labor? If yes, you're in Scenario C. Budget for expertise, not just equipment.
Most mistakes happen when people treat a Scenario C project like a Scenario A purchase (buying sports lighting on unit price) or a Scenario B purchase like Scenario A (mixing brands because they're "compatible" in theory). If you're not sure which bucket you're in, ask: what's the most expensive thing that could go wrong? That usually tells you where the decision risk lives.
What I'd Tell Someone Starting This Today
I've tracked about $180,000 in cumulative lighting spending since 2019. The pattern is consistent: the products are rarely the problem. The problem is using one decision framework for three different kinds of purchases.
So separate them. Use a ballast compatibility checklist for retrofits. Use a standardization and maintenance-cost worksheet for new installs. Use a service-budget template for specialty work. None of these are complicated. They just aren't the same document—and that's the whole point.
