LED Area Light (Shoebox) Buying Guide: Wattage, Distribution, Pole Height (2026)
Complete LED area light buying guide for parking lots and outdoor commercial spaces. Covers wattage by pole height, Type III vs V distribution, IES RP-20 compliance, dark sky options, and surge protection.
# LED Area Light (Shoebox) Buying Guide
LED area lights — also called shoebox lights due to their shape — are the standard fixture for parking lots, roadways, and outdoor commercial areas. This guide covers everything you need to specify the right fixture.
Wattage by Pole Height
| Pole Height | LED Wattage | Replaces | Coverage per Fixture |
|---|---|---|---|
| 15-20 ft | 100-150W | 250-400W MH/HPS | ~60×60 ft |
| 20-25 ft | 150-200W | 400W MH/HPS | ~70×70 ft |
| 25-30 ft | 200-300W | 400-750W MH/HPS | ~80×80 ft |
| 30-35 ft | 300-400W | 750-1000W MH/HPS | ~100×100 ft |
| 35-40 ft | 400-600W | 1000-1500W MH/HPS | ~120×120 ft |

Distribution Types Explained
Type III
- Pattern: Forward throw, asymmetric
- Best for: Perimeter poles along building edges, property lines, walkways
- How it works: Projects light forward (away from pole), minimal backlight
- Use when: Pole is near a building or property boundary
Type V
- Pattern: Circular, symmetric in all directions
- Best for: Center-of-lot poles, intersections, open areas
- How it works: Equal light distribution in all directions
- Use when: Pole is surrounded by area needing light on all sides
Quick Selection
| Pole Location | Distribution |
|---|---|
| Against building wall | Type III |
| Lot perimeter | Type III |
| Center of parking lot | Type V |
| Road intersection | Type V |
| Drive aisle between buildings | Type III (both sides) or Type V |

IES RP-20 Compliance
IES RP-20 is the standard for parking lot lighting. Key requirements:
| Area Type | Minimum FC | Uniformity (max:min) |
|---|---|---|
| Open parking (low activity) | 0.5 FC | 20:1 |
| Open parking (medium activity) | 1.0 FC | 15:1 |
| Open parking (high activity) | 2.0 FC | 10:1 |
| Covered parking | 5.0 FC | 10:1 |
| ATM/pedestrian areas | 5.0 FC | 4:1 |

Critical Specifications
Surge Protection
Outdoor LED fixtures are vulnerable to lightning-induced surges. Require 10kV minimum surge protection for all area lights. Without it, a single lightning strike can destroy multiple fixtures at once. Auvolar area lights include 10kV surge protection standard.
IP Rating
IP66 minimum for outdoor area lights. IP66 means dust-tight + powerful water jets (driving rain, pressure washing). IP65 (low-pressure water) is acceptable for covered areas but not recommended for exposed outdoor use.Wind Load
Area lights mount on poles at height — wind resistance matters. Specify EPA (Effective Projected Area) and verify the pole/arm can handle the fixture weight plus wind load. Typical LED area light EPA: 1.0-2.5 sq ft. Lighter and lower EPA than equivalent metal halide.
Dark Sky Compliance
If required by local code or desired for environmental reasons, specify full cutoff fixtures with BUG rating U0 (zero uplight). This directs all light downward, eliminating light pollution and wasted energy directed at the sky.

Energy Savings Example
100-Fixture Parking Lot (400W HPS → 200W LED)| HPS | LED | |
|---|---|---|
| Fixture wattage | 465W (with ballast) | 200W |
| Annual energy cost (4,380 hrs) | $24,462 | $10,512 |
| Annual maintenance | $8,000 | $0 |
| Annual savings | — | $21,950 |
| Utility rebate (SDG&E) | — | $10,000 one-time |
| Net project cost | — | $15,000 |
| Payback | — | 8.2 months |
