For Bay Area business owners, an LED lighting retrofit is one of the fastest-paying upgrades there is: swapping old fluorescent or HID lighting for LED typically cuts lighting energy use 50–70%, and with utility rebates the payback often lands in 1–3 years. Lower bills, better light, far less maintenance, and rebates that shrink the upfront cost. Here's what it involves and what to expect.
Pacific Edge Electric and Solar is a licensed C-10 electrical contractor (CA #1143455) in Los Gatos. We do commercial LED retrofits across the South Bay — offices, warehouses, retail, parking areas — so this is the practical view.
Why LED retrofits pay off so fast
- Energy savings. LEDs use 50–70% less power than fluorescent or HID for the same or better light output — a direct cut to your electric bill.
- Maintenance savings. LEDs last far longer, so you slash relamping labor and ladder time — a real cost in high-bay warehouses and parking structures.
- Rebates. Utility and efficiency-program rebates frequently cover a meaningful chunk of the project, shortening payback further.
- Better environment. Brighter, more consistent, flicker-free light improves safety and how a space feels to customers and staff.
What a retrofit typically includes
A proper commercial retrofit is more than swapping bulbs. It usually involves replacing fixtures or installing LED retrofit kits, and often adding controls — occupancy sensors, daylight harvesting, and scheduling — that stack more savings on top of the LED efficiency. We start with a lighting audit: count and categorize the existing fixtures, measure light levels, then design a replacement that hits the right brightness for each space (a warehouse aisle, an office, a parking lot all need different lighting) while maximizing rebate eligibility.
Rough economics
| Metric | Typical result |
|---|---|
| Lighting energy reduction | 50–70% |
| Payback (after rebates) | 1–3 years |
| Fixture lifespan increase | Several times longer than fluorescent/HID |
Project cost depends on fixture count, ceiling height, and controls; the audit produces a firm number and the projected savings and rebate.
Don't leave the rebate on the table
Rebate programs have rules — qualifying products, pre-approval steps, documentation — and a contractor who does retrofits regularly designs the project to capture them and handles the paperwork. Skipping that can mean leaving real money unclaimed. We build the rebate into the proposal so you see the net cost, not just the gross.
Pair it with the rest of your electrification
Because we're an electrical contractor, a lighting retrofit can fold into other commercial work — EV charging, a service upgrade, or solar — on one coordinated project. If you're already thinking about commercial solar, doing the LED retrofit at the same time lowers your load first, so you can right-size the solar and save on both.

Frequently asked questions
How much can an LED retrofit save my business?
LED retrofits typically cut lighting energy use 50–70%, plus major maintenance savings from longer-lasting fixtures. With utility rebates, payback is often 1–3 years.
Are there rebates for commercial LED lighting?
Frequently, yes — utility and energy-efficiency programs often rebate a significant portion of a qualifying retrofit. Programs have specific rules, so a contractor experienced with retrofits should design the project to capture the rebate and handle the paperwork.
Is an LED retrofit just changing the bulbs?
No — a proper commercial retrofit replaces fixtures or installs LED kits and often adds controls like occupancy sensors and daylight harvesting, designed around the right light levels for each space. It starts with a lighting audit.
Should I do LED lighting before solar?
Often yes. Reducing your lighting load first means you can right-size a solar system to a lower demand, improving the economics of both projects — and they can be done together.
Savings and payback vary by facility, existing lighting, and current rebate programs; an audit produces firm figures. Written by Adam Aksoy, licensed C-10 electrical contractor (CA #1143455), Pacific Edge Electric and Solar.
