Commercial Lighting Is One of the Most Accessible Ways to Reduce Operating Costs
Lighting accounts for roughly 20–30% of commercial electricity consumption in typical office, retail, and warehouse environments. In older buildings, and there are plenty of them in Tulsa and Broken Arrow, that percentage skews higher, especially in spaces still running T12 fluorescent fixtures, metal halide high-bays, or incandescent accent lighting.
An LED lighting retrofit replaces those older systems with modern LED technology that uses significantly less energy, produces better light quality, and lasts far longer. The math is usually compelling. This guide gives Tulsa business owners a clear picture of what a commercial LED retrofit involves, what to look for in a proposal, and what honest ROI looks like.
What Gets Replaced in a Commercial LED Retrofit
Fluorescent Fixtures
T12 and T8 fluorescent tubes are the most common replacement targets in office and retail spaces. Modern LED tube replacements or new LED fixtures provide equivalent or better light levels while using 40–60% less energy. They also eliminate the flicker that fluorescent lights produce as they age something employees in open office environments notice immediately.
HID (High-Intensity Discharge) High-Bays
Metal halide and high-pressure sodium fixtures are standard in warehouses, manufacturing facilities, and large retail spaces. They produce a lot of light but require significant warm-up time, produce inconsistent color rendering, and consume 250–1,000 watts per fixture. LED high-bay replacements for the same application run 100–300 watts with better color rendering, instant-on operation, and 50,000+ hour lifespans.
Exterior and Parking Lot Lighting
Parking lot poles and building exterior fixtures are often the oldest and least efficient in a commercial property’s inventory. LED shoebox fixtures and wall packs produce better coverage, dramatically lower energy consumption, and significantly reduced maintenance costs. Metal halide fixtures burn out far more frequently than LED.
How to Read a Retrofit Proposal
A credible LED retrofit proposal should include:
- A fixture-by-fixture inventory of what’s being replaced
- Current wattage vs. proposed LED wattage per fixture type
- Estimated annual energy savings in kilowatt-hours and dollars (based on your actual utility rate)
- Simple payback period calculation
- Fixture specifications, not just brand names; lumens, color temperature (CCT), CRI
- Labor scope: what installation involves and how long it will take
If a proposal gives you a single lump-sum number without breakdown, ask for the detail. Understanding what you’re getting for the investment is your right as a buyer.
The Buxton Standard: The Numbers First, the Sale Second
How Buxton approaches commercial lighting retrofits:
We assess your current fixtures, calculate actual energy consumption, model the savings at your real utility rate, and give you a clear project cost. You’ll see the payback period before you make any decision. If the math doesn’t work for your situation, we’ll tell you. No pressure, no inflated projections.
