The most common question facility managers ask before starting an LED retrofit is: how much will this cost, and how quickly will I get it back? The honest answer is it depends — but the range is knowable, and the math almost always works decisively in favor of doing the project.
This guide breaks down typical cost ranges by fixture type and facility size, explains what drives pricing variation, quantifies the impact of utility rebates, and gives realistic payback expectations based on 2025–2026 project data.
Typical Cost Ranges
Commercial LED retrofit costs vary widely based on fixture type, count, facility complexity, and labor requirements. Here are rough installed cost benchmarks before rebates for common applications in 2026:
| Fixture Type | Legacy Source | Installed Cost / Fixture | Typical Savings | Payback (post-rebate) |
|---|---|---|---|---|
| LED High-Bay (UFO) | 400W Metal Halide | $250–$400 | 60–75% | 12–20 months |
| LED Troffer (2×4) | Fluorescent T8 | $75–$130 | 45–55% | 18–30 months |
| LED Wall Pack | HPS/MH Wall Pack | $200–$350 | 60–70% | 14–24 months |
| LED Area Light | HPS Pole Light | $350–$600 | 60–70% | 18–30 months |
| LED Strip/Linear | Fluorescent T8 | $60–$110 | 40–50% | 20–36 months |
These figures represent installed cost — product plus licensed labor. Purchasing fixtures without professional installation is rarely advisable for commercial facilities: improper installation voids warranties, creates liability, and often sacrifices rebate eligibility.
What Drives Cost Variation
1. Fixture Count and Facility Size
Larger projects cost less per fixture due to volume purchasing and efficient crew scheduling. A 50-fixture office retrofit will have a higher per-unit cost than a 500-fixture warehouse project. For national or multi-site rollouts, economies of scale can reduce per-fixture costs significantly.
2. Ceiling Height and Access
Labor cost increases with ceiling height. Facilities with ceilings above 30 feet require lifts or aerial work platforms — adding $50–$150 per fixture in labor cost. This is why high-bay replacements cost more per unit than low-bay troffer work.
3. Full Replacement vs. Retrofit Kit
LED retrofit kits that convert existing fixture housings to LED are less expensive than full fixture replacement. However, kits are only appropriate when existing fixtures are in good condition. For metal halide high-bays, full fixture replacement is usually specified because MH housings aren't engineered for LED thermal management.
4. Controls Integration
Adding occupancy sensors, daylight harvesting, or centralized controls adds $30–$80 per control point. Controls typically pay for themselves quickly — adding 15–30% energy savings on top of base LED performance — and they're rebate-eligible alongside the fixtures.
"For most commercial facilities, controls pay for themselves in 6–12 months through additional savings beyond LED alone — making them one of the highest-ROI additions to any retrofit project."
How Utility Rebates Change the Math
Rebates are the most underutilized variable in commercial LED economics. Many facility managers proceed without them — either because they don't know they're available, or because navigating the application seems complicated. The result is paying 20–40% more for the same project.
| Facility Type | Gross Project Cost | Typical Rebate | Net Cost | Payback Improvement |
|---|---|---|---|---|
| 250-fixture warehouse | $85,000 | $25,000 (29%) | $60,000 | 8 months faster |
| 150-fixture office | $18,000 | $4,500 (25%) | $13,500 | 6 months faster |
| 80-fixture parking lot | $36,000 | $9,000 (25%) | $27,000 | 10 months faster |
| 400-fixture multifamily | $42,000 | $12,000 (29%) | $30,000 | 7 months faster |
Key facts about utility rebates in 2026:
- Most programs require DLC-qualified products — standard for reputable contractors
- Pre-approval is required before installation begins for most utility programs
- Industrial/warehouse projects often qualify for the largest rebate totals
- Controls are rebate-eligible alongside fixtures — stack the savings
- Programs have annual budgets that fill — earlier application means higher capture

LEARN ABOUT REBATESPayback Period by Facility Type
Payback period — the time until energy savings equal the net project cost — is the primary financial metric for most facilities. Here's what to expect based on typical operating hours and energy rates:
| Facility Type | Daily Hours | Legacy Source | Typical Payback | 10-Year Net Savings |
|---|---|---|---|---|
| Warehouse / Distribution | 16–24 hrs | Metal Halide | 12–18 months | Very high |
| Manufacturing / Industrial | 16–24 hrs | MH / HPS | 12–20 months | Very high |
| Multifamily Common Areas | 12–20 hrs | Fluorescent | 14–20 months | High |
| Parking / Exterior | 10–14 hrs | HPS / MH | 18–28 months | High |
| Commercial Office | 10–14 hrs | Fluorescent T8 | 20–30 months | Moderate–High |
| Retail | 12–16 hrs | Fluorescent / Halogen | 18–26 months | Moderate–High |
The fastest-payback projects are high-wattage HID sources running long operating hours. A 24/7 warehouse replacing 400W metal halide with 150W LED achieves payback faster than almost any other commercial application.
Beyond Payback: 10-Year ROI and Maintenance Savings
Payback period tells you when you break even. The better metric is 10-year net savings — the cumulative benefit over a typical planning horizon.
A warehouse that spends $85,000 gross ($60,000 net after rebates) on an LED retrofit and saves $40,000 per year in energy costs will accumulate $400,000 in savings over 10 years — a net return of $340,000 on a $60,000 investment. That's a 567% ROI before accounting for maintenance savings.
Maintenance savings are significant and often underestimated:
- LED fixtures have rated lifespans of 50,000+ hours vs 10,000–20,000 for MH and fluorescent
- Elimination of lamp replacement labor and lift rental for high-bay facilities
- Reduced facilities staff time managing lamp failures and emergency replacements
- Fewer disruptions to operations from unplanned outages
How to Get Your Actual Numbers
The ranges in this guide are useful for budgeting and board presentations — but not precise enough for a capital investment decision. Your actual savings, project cost, and payback period depend on your specific fixture types, utility rates, operating patterns, and available rebate programs.
The right starting point is a professional site audit — which Echelon provides at no cost and no obligation. You'll receive a full fixture inventory, energy baseline measurement, savings projection, rebate identification, and ROI timeline specific to your facility within 48 hours of the site visit.
