Parking lot LED: biggest energy savings of any retrofit.
Parking lot LED conversion from HID (high-pressure sodium, metal halide) delivers 60-75% energy savings, dramatically better light quality, and 5-10x longer fixture life.

Parking lot LED conversion: replace older HID fixtures (typically 250W-400W metal halide or HPS) with modern LED fixtures (typically 80W-150W LED). Energy savings 60-75% per fixture. Light quality improvement substantial — LED color rendering vs orange HPS or yellow MH is dramatic. Maintenance reduction significant — LED 50,000+ hour lifespan vs HID 8,000-15,000 hour ballast/lamp combined lifespan. Cost per fixture installed $400-$1,200 depending on pole work scope.
01Why parking lot LED retrofit is high-value.
Operating hours: parking lot lighting typically operates dusk-to-dawn (10-14 hours per night) plus daytime in covered/garage applications. High annual operating hours mean meaningful absolute energy savings per fixture. For a 25-fixture parking lot at 12 hours nightly: $1,800-$3,600 annual savings vs old HID.
Maintenance avoidance: HID lighting requires ballast replacement every 3-5 years and lamp replacement every 2-3 years. Service truck visits to replace failed HID lamps in parking lot poles cost $200-$500 per visit. Over a 10-year period, avoided service calls easily equal initial retrofit investment.
02What parking lot retrofit involves.
Fixture replacement
Remove existing HID fixture from pole, install LED fixture. Typically same mounting bracket if pole compatibility allows; sometimes new bracket required. 1-2 hours per pole including bucket truck setup.
Photocell update
Existing photocells (dusk-to-dawn sensors) sometimes need replacement for LED compatibility. Photocell-controlled HID circuits sometimes need adjustment for LED operating characteristics. Modest scope addition.
Control upgrade options
Networked parking lot controls (DMX, occupancy-responsive) add significant value for larger lots — dimming to 30-50% during unoccupied late-night hours, full output when motion detected, schedule-based control for known low-occupancy periods. Adds $50-$150 per fixture but increases savings 20-30% beyond fixture replacement alone.
03Common Marin parking lot retrofit projects.
Small commercial parking (10-25 fixtures): scope $4,500-$15,000 total project. Payback 24-36 months from energy savings; faster with utility rebates. Mid-sized commercial parking (25-75 fixtures): $12,000-$45,000 project. Payback 18-30 months with rebates.
Larger commercial or shared parking (75-200 fixtures): $40,000-$150,000 project, often phased over multiple budget cycles. Bay Area shopping centers and large multi-tenant commercial commonly in this scope range. Mall and large institutional parking can run 500+ fixtures, $200,000-$700,000+ in phased projects.
Common questions.
Can I retrofit existing poles or do I need new ones?
Most existing poles accept LED retrofit fixtures with existing mounting hardware. New poles required only if existing poles have structural issues (corrosion, damage), inadequate height for current parking lot standards, or owner upgrades to taller/sturdier poles. Most Marin retrofits reuse existing poles.
What about parking garage lighting?
Similar retrofit case with stronger payback — garages operate longer hours (often 24/7), so energy savings accumulate faster. LED color quality dramatically better than fluorescent or HID typical in older garages. Combined with occupancy sensors, can deliver 70-85% energy reduction. Common retrofit scope for Marin commercial parking garages.
Are there rebates for parking lot LED?
Yes — PG&E and BayREN both offer parking lot LED rebates. Prescriptive rebates typically $50-$200 per qualifying fixture replacement. For larger projects, custom rebates available. We process rebate applications as part of project scope.
How do you handle pricing — flat fee or hourly?
Both, depending on scope. Routine service calls and predictable scope (panel replacement, EV charger install, transfer switch install, fixture replacement) are flat-fee quoted up front. Diagnostic visits and emergency scope are hourly because we don't know what we'll find. Either way, you get a written quote before work starts on anything significant, and we don't proceed beyond the quote without your sign-off.
How quickly can you schedule?
Depends on scope and season. Emergency dispatch: same-day across Marin County (1-3 hours business hours, 1-4 hours after-hours). Same-day standard service: 3-6 hours from call when capacity allows; otherwise next business day. Scheduled service work: 1-3 weeks typical. Larger projects requiring permits and PG&E coordination: 4-12 weeks depending on scope. We're upfront about timeline at the quote stage.
What warranty do you offer on work?
Our standard residential warranty: 2 years on labor, manufacturer warranty on parts (varies by product — typically 1-10 years). Major installs (panels, generators, EV chargers) often have longer manufacturer warranties (5-10 years). If there's an issue with our work in the warranty period, we come back and fix it at no cost. We also stand behind work past warranty — repeat customers and referrals matter more than a transactional fix.
Are you licensed and insured?
