The Fork in the Road: Retrofit or Replace?
If you're managing a commercial lighting project and you've landed on Cree as your brand, you're probably staring down a specific choice: should you spec Cree retrofits (the 6-inch LED retrofit trims, the pole light conversion kits) or go all-in on new Cree fixtures?
I've been a procurement manager for a mid-sized commercial property group for about seven years now. We manage a portfolio of maybe 40 buildings – office spaces, warehouses, retail. Over that time, I've tracked every lighting order in our system. When I audited our 2023 spending, I pulled up 18 different Cree orders alone. So I've put both approaches through the wringer.
Let's break down the real difference across the dimensions that matter to a budget: total cost of ownership, labor and downtime, and performance ceiling.
Dimension 1: Total Cost of Ownership (TCO) — The Retrofit Advantage
This is where retrofits usually win on paper, but the numbers are closer than you'd think.
Upfront Cost: Retrofits
A Cree 6-inch LED retrofit trim (the kind that replaces the old can light trim and bulb) runs somewhere around $25-$40 per unit at distributor pricing, as of late 2024. A Cree pole light conversion kit for a parking lot? Maybe $100-$180, depending on the wattage and optics. You're reusing the existing housing or pole. You're not pulling new wire.
Upfront Cost: New Fixtures
A full new Cree recessed downlight fixture (housing + trim) is closer to $45-$70. A new Cree parking lot pole light fixture is $200-$350. That's before you factor in any structural work, like if the old housing is a weird size or the pole base is corroded.
On paper, the retrofit saves you 30-40% on hardware alone. But here's the thing: that math assumes the existing infrastructure is sound. Honestly, I'm not sure why some building managers assume it always is. My best guess is they don't want to open walls or dig up pole bases to check.
I've never fully understood the cost of that optimism. In one warehouse retrofit we did in Q2 2024, we discovered that 12% of the existing junction boxes were incompatible with the Cree retrofit brackets. That added $45 per fixture in adapters and labor. The 'cheap' retrofit ended up costing only 15% less than a new fixture would have.
Long-Term TCO: New Fixtures Catch Up
Retrofits have a shorter lifespan, generally speaking. A Cree LED retrofit trim might be rated for 50,000 hours. A new Cree fixture with a better thermal path (like a commercial downlight with a cast-aluminum heat sink) could be 70,000-100,000 hours. Over 10 years, you might replace the retrofit once. You likely won't touch the new fixture. That closes the gap significantly.
Verdict: If your existing housings or poles are in good shape and standard sizes, retrofit wins on TCO. If you're unsure about the infrastructure, new fixtures are the safer bet.
Dimension 2: Labor and Downtime — Retrofit Runs Away With It
People think retrofits are just about cheaper hardware. Actually, the real savings is in labor and business disruption. The causation runs the other way: retrofits save you money because they save you time, not just because the part costs less.
Installation Speed
A Cree 6-inch retrofit takes about 5-10 minutes per fixture for an electrician. It's a trim twist-in or a spring clip. No box removal, no drywall repair.
A new fixture? Plan on 20-40 minutes. You've got to disconnect the old housing, possibly patch the ceiling, and then install and wire the new housing. For a surface-mounted pole light, it's even worse – you might need a bucket truck if you're replacing a pole-mounted fixture.
For our 40-building portfolio, the difference in labor alone was around $7,500 on a typical 200-fixture retrofit project vs. a new install. That's not nothing.
Business Disruption
This is the hidden cost. A retrofit in a parking lot? You can usually shut down one section, change 20 lights in an hour, and reopen. A new pole light install might require a full night of work and a trench for new conduit if you're upgrading the pole.
In an office, retrofits can be done during business hours if the ceiling grid is accessible. New fixtures? You're probably working nights or weekends. I'd say overtime labor adds 30-50% to the project cost, but don't quote me on that exact number—it depends on union rules and your specific crew.
Verdict: Retrofit wins unless your building is empty or you're already planning a full renovation.
Dimension 3: Performance Ceiling — New Fixtures, No Contest
This is the dimension that surprises a lot of people. The assumption is that a Cree LED is a Cree LED, and the retrofit will perform the same as a new fixture. The reality is that the housing matters.
Heat Management
A new Cree fixture is designed as a system: the LED chip, the driver (that's the driver for LED lights), and the heat sink are all engineered together. Retrofits drop a module into an existing housing that might be thermally insulated, or metal that conducts heat differently. If the housing traps heat, the LED chip degrades faster.
I compared lumen output after 18 months on a retrofit install in a warehouse vs. a new Cree high bay in our main facility. The retrofit was noticeably dimmer – maybe 10-15% less output. I'd have to check the sensor data to be sure, but the maintenance team flagged it.
Optics and Control
New Cree fixtures have better optics. The downlight trim and the reflector are matched to the LED board. A retrofit trim might have a wider beam, or a less diffused look, because it's adapting to an existing can. For a parking lot, a new Cree pole light fixture with precision optics will give you more uniform light on the ground and less light trespass. The retrofit kit? Fine for general illumination, but not as good for precise lighting.
Verdict: New fixtures win if you need maximum light output or precise beam control. If you just need 'good enough' illumination for a storage area or a walkway, the retrofit is fine.
Conclusion: How to Decide Between Cree Retrofits and New Fixtures
There's no one-size-fits-all answer here. I've made both decisions – and regretted at least one.
I recommend Cree retrofits for:
- Retrofit projects where the existing housing is in good shape and standard size. (Think 6-inch cans in drop ceilings or standard pole mounts in parking lots.)
- Projects where minimizing downtime is critical. (Retail stores, occupied offices.)
- Budget-constrained projects where you need the lowest upfront cost.
I recommend new Cree fixtures for:
- New construction or gut renovations. (Don't put old wine in new bottles.)
- Applications requiring maximum light output. (High-bay warehouses, security lighting.)
- Projects where you plan to keep the fixture for 15+ years. (The longer lifespan makes the upfront cost worth it.)
One more thing: if you're comparing quotes for a project and you see a retrofit bid that's 40% cheaper than a new fixture bid, ask the contractor to walk you through the assumptions. Are they including adapters for non-standard housings? Is the labor estimate for a straight swap or are they expecting complications? A 'cheap' retrofit can turn into a costly headache if the infrastructure isn't there.
