When a property owner evaluates a commercial LED retrofit, they almost always focus on the energy savings. That's understandable — energy costs are a single line item on the utility bill. They're visible, measurable, and easy to compare before and after.
The bigger number, in most cases, is hiding in the maintenance column. And it's usually bigger than people realize because maintenance costs hide in a dozen different places.
Where lighting maintenance actually costs money
Here's what most property owners think lighting maintenance costs:
That's the number they compare against LED projects. It's dramatically wrong. Here's what lighting maintenance actually costs when you count everything:
**Lamp cost** — Commercial metal halide lamps run $20 to $60 each. High-quality exterior HID can run $80 to $120 for larger fixtures.
**Ballast replacement** — Ballasts fail on their own schedule, typically after 2-4 lamp replacements. A magnetic ballast runs $40 to $150. Labor to replace is 2-3x a lamp replacement.
**Truck/lift rental** — To change a pole-mounted or high-bay fixture, you need a bucket truck or scissor lift. Daily rental on a bucket truck runs $300 to $700 per day depending on boom height. For a single fixture change, you're paying for at least a half-day.
**Labor time** — A commercial lamp change isn't 10 minutes. It's a site visit, a truck positioning, a safety setup, the actual work, documentation, cleanup, and transit. Loaded labor rate for a commercial electrician runs $80 to $150 per hour. A typical lamp change is 1.5 to 3 hours of actual labor.
**Travel time and minimum call-out** — Most service contractors charge a 2-4 hour minimum for any service call. If you're calling them out for one fixture, you're paying for 2-4 hours of labor even if the actual work takes 45 minutes.
**Opportunity cost** — If a parking lot light is out, tenants complain. Customers notice. Evening foot traffic drops. For retail properties, dim spots in the parking lot have measurable impact on evening revenue. For office properties, they affect tenant satisfaction and renewal decisions.
**Emergency premium** — Fixtures don't fail on convenient schedules. When something fails during an event, during a holiday, or after business hours, emergency service rates apply. Emergency response rates are typically 1.5x to 2x standard rates.
The real cost per fixture per year
When we actually add it all up across commercial portfolios, the true all-in cost of legacy HID lighting maintenance runs approximately $17.25 per fixture per year.
Here's how that breaks down for a typical 400W metal halide pole fixture:
We use $17.25 per fixture per year as a conservative weighted average across typical commercial portfolios. Actual costs are often higher for properties with high pole counts, remote locations, or strict SLAs.
Compare that to LED maintenance at roughly $0.54 per fixture per year (driver failure rate times replacement cost, annualized). That's a 97 percent maintenance cost reduction per fixture.
Why this gets missed in most LED evaluations
LED proposals from most contractors show energy savings prominently and treat maintenance savings as a minor bonus. A typical proposal might list:
The maintenance number is usually calculated as lamp-only — "we save 50 lamps per year at $30 each equals $1,500." That's not maintenance savings. That's lamp cost reduction.
True maintenance savings for the same property (accounting for lift rental, labor, emergency response, opportunity cost) might be $5,000 to $10,000 per year. The total annual savings shifts from $23,500 to $27,000 to $32,000. The payback period improves from 3 years to 2.2 years.
This is one of the single biggest mistakes property owners make when evaluating LED proposals — they use the contractor's maintenance number without auditing it against their actual operating history.
How to calculate your real maintenance cost
If you want to know what your current lighting maintenance is actually costing you, pull the last 24 months of:
Divide the total annual cost by your current fixture count. You'll probably get a number between $12 and $25 per fixture per year. That's your real maintenance cost.
Now multiply that by your fixture count to get total annual maintenance spend. Subtract the LED maintenance baseline ($0.54 × fixture count). That's your real maintenance savings from an LED retrofit.
The compound effect over 10 years
Over a 10-year LED fixture lifetime, maintenance savings compound dramatically:
For larger properties, the numbers scale proportionally. A 1,000-fixture portfolio generates $167,100 in cumulative maintenance savings over 10 years — not counting the energy savings.
What this means for LED project justification
If you're evaluating an LED retrofit and the contractor's proposal shows maintenance savings as a minor line item, push back. Ask them to show you the calculation. Ask what maintenance cost per fixture they used. Ask whether they included lift rental, emergency response, and opportunity cost.
If their maintenance calculation is weak, their payback number is wrong. Ask them to rebuild it with realistic assumptions — or calculate it yourself using your actual historical maintenance costs.
The LED retrofit is usually a better deal than the proposal shows. But only if you count the maintenance correctly.
The bigger story
Commercial lighting is unusual among operating costs in that the hidden maintenance layer is often larger than the visible energy layer. Most operating expenses don't work that way.
When property owners realize this, the conversation shifts from "should we do LED?" to "why haven't we done this already?" The maintenance savings alone justify most commercial LED retrofits — even before counting the energy savings.
If you've been delaying a lighting upgrade because the payback looks marginal, run the maintenance numbers with realistic assumptions. The answer usually changes.
