LED Area Light vs Metal Halide for Parking Lots: Full Cost Comparison (2026)
Detailed comparison of LED area lights vs metal halide for parking lots. Energy costs, maintenance, light quality, ROI analysis with real numbers.
If your parking lot still runs on metal halide (MH) or high-pressure sodium (HPS) lights, you're spending 2-3x more on electricity than you need to — and that's before counting the maintenance costs.
This guide breaks down exactly how LED area lights compare to metal halide for parking lots, with real numbers and ROI calculations.
The Quick Answer
| Factor | Metal Halide | LED Area Light |
|---|---|---|
| Energy use (equivalent output) | 400W | 150W |
| Annual electricity cost (per fixture) | $350 | $131 |
| Lifespan | 15,000-20,000 hours | 50,000-100,000 hours |
| Maintenance | Re-lamp every 2-3 years | Zero for 10+ years |
| Light quality | Degrades 40% before failure | Maintains 90%+ throughout life |
| Warm-up time | 5-15 minutes | Instant on |
| Color rendering (CRI) | 65-70 | 70-80+ |
| Rebate eligible | No | Yes (DLC certified) |
Energy Cost Comparison: Real Numbers
Assumptions:- Operating 12 hours/night, 365 nights/year
- Electricity rate: $0.22/kWh (California average)
- 50-fixture parking lot
Metal Halide (400W fixtures)
- Actual system wattage: 458W (includes ballast loss)
- Annual energy per fixture: 458W × 12h × 365 = 2,006 kWh
- Annual cost per fixture: 2,006 × $0.22 = $441
- 50-fixture annual cost: $22,050
LED Area Light — Auvolar OT Series 150W
- System wattage: 150W (no ballast loss with LED drivers)
- Annual energy per fixture: 150W × 12h × 365 = 657 kWh
- Annual cost per fixture: 657 × $0.22 = $145
- 50-fixture annual cost: $7,250
Annual Savings: $14,800
That's $14,800/year in electricity savings alone for a 50-fixture parking lot in California.
Maintenance Cost Comparison
Metal Halide Maintenance
Metal halide lamps degrade significantly over their life and need replacement every 2-3 years:
- Lamp cost: $25-$45 each
- Ballast replacement (every 5-7 years): $50-$100 each
- Bucket truck rental: $250-$500 per visit
- Electrician labor: $75-$150/hour
- Typical maintenance cost: $150-$300 per fixture per re-lamp cycle
- For 50 fixtures every 3 years: $3,750-$7,500
LED Area Light Maintenance
- No lamp changes for 10+ years (100,000-hour rated life)
- No ballast — integrated LED driver
- Only maintenance: occasional cleaning
- 10-year maintenance cost: essentially $0
Total Cost of Ownership: 10-Year Analysis
50-Fixture Parking Lot
Metal Halide (keep existing):| Cost Item | 10-Year Total |
|---|---|
| Electricity | $220,500 |
| Lamp replacements (3 cycles) | $11,250 |
| Ballast replacements | $5,000 |
| Labor & equipment | $7,500 |
| Total | $244,250 |
| Cost Item | 10-Year Total |
|---|---|
| Fixture cost (50 × $120) | $6,000 |
| Installation labor | $3,000 |
| Utility rebate (SCE, -$3,750) | -$3,750 |
| Electricity | $72,500 |
| Maintenance | $0 |
| Total | $77,750 |
10-Year Savings: $166,500
ROI: 2,775% — or put another way, every $1 spent on LED fixtures saves $27.75 over 10 years.Light Quality Comparison
Lumen Depreciation
Metal halide lights lose 30-40% of their brightness within the first year of operation, even though the lamp still "works." This means:
- New MH 400W: ~36,000 lumens
- After 1 year: ~22,000 lumens
- At end of life: ~18,000 lumens
LED area lights maintain 90%+ of initial lumens for their entire rated life:
- Auvolar OT Series 150W: 22,500 lumens initially
- After 5 years: ~21,000 lumens (L90)
- After 10 years: ~18,000 lumens (L70)
Color Quality
- Metal halide: CRI 65-70, shifts to green/pink as lamp ages
- LED: CRI 70-80+, consistent color throughout life
- LED provides better visibility for security cameras
- Whiter light improves safety perception
Instant On/Off
- Metal halide: 5-15 minute warm-up, 10-20 minute restrike after power interruption
- LED: Instant on, instant restrike
- Critical for security and emergency situations
Which LED Area Light Replaces Which Metal Halide?
| Old Metal Halide | LED Replacement | Auvolar Model | Price |

Frequently Asked Questions
Q: Can I use the existing pole and arm?A: Yes. All Auvolar area lights come with multiple mounting options (slip fitter, direct arm, yoke mount, trunnion) that fit standard 2-3/8" tenon poles.
Q: Do I need to change the wiring?A: Auvolar OT Series accepts 120-277V universal voltage. In most cases, no rewiring is needed.
Q: How long does installation take?A: A skilled electrician can swap one fixture in 15-30 minutes. A 50-fixture parking lot typically takes 2-3 days.
Q: What about dark sky / light pollution?A: The Auvolar PLB Series has a BUG rating of 0-0-0, meaning zero uplight and zero backlight — the best possible rating for dark sky compliance. Price starts at $200.
Q: Where can I buy LED parking lot lights in California?A: Auvolar ships from City of Industry, California. Same-day pickup available, next-day delivery statewide. Call (626) 342-8856 or visit auvolar.com.
Conclusion
The math is clear: LED area lights beat metal halide in every category — energy cost, maintenance, light quality, lifespan, and total cost of ownership. With California utility rebates covering 30-50% of fixture costs, the payback period is often under 6 months.
If you're still running metal halide parking lot lights, every month you wait costs money. Contact Auvolar at (626) 342-8856 for a free lighting assessment and rebate estimate.
