Essential Aspects of Outdoor Parking Lot Lighting Design

Properly designed outdoor parking lot lighting enhances safety, security, and convenience for users. Consider the following essential aspects to create an effective lighting system.

1. Lighting Levels

Adequate lighting levels ensure visibility and prevent accidents. The recommended average maintained illuminance for parking lots is 0.9 foot-candles (9.7 lux). Consider installing higher lighting levels near entrances, exits, and pedestrian walkways.

2. Uniformity

Uniform lighting distribution minimizes glare and shadows. Aim for a uniformity ratio of 3:1 or less, meaning the brightest spot should be no more than three times brighter than the darkest spot.

3. Light Source

LED fixtures are highly efficient, long-lasting, and emit minimal glare. Other options include high-pressure sodium (HPS) and metal halide (MH) lamps, which are less energy-efficient but provide good color rendering.

4. Pole Heights and Spacing

Pole heights and spacing determine the lighting coverage and uniformity. Taller poles provide broader coverage, while closer spacing reduces shadows. Generally, poles should be 20-30 feet high and spaced 100-150 feet apart.

5. Fixture Selection

Choose fixtures with a distribution pattern that suits the parking lot layout. Asymmetrical fixtures are suitable for narrow areas, while symmetrical fixtures provide even coverage for larger spaces.

6. Control System

Dimming controls can reduce energy consumption and extend fixture life. Consider installing motion sensors to activate lighting only when needed. Photocells can switch lights on at dusk and off at dawn.

7. Mast Arm Extensions

Mast arm extensions extend fixtures over parking spaces, providing better coverage and preventing light spillage onto surrounding areas.

8. Accessibility and Maintenance

Ensure poles are easy to access for maintenance and bulb replacements. Consider using breakaway bases or hinged poles to minimize damage from vehicle collisions.

9. Security

Proper lighting deterrs crime and makes users feel safer. Install fixtures with motion detection capabilities and aim lights toward potential hiding spots.

10. Aesthetics

Consider the aesthetics of the lighting system by choosing fixtures that complement the surrounding architecture and landscape. Avoid excessive glare and light pollution that can impact neighbors.

By incorporating these essential aspects into your outdoor parking lot lighting design, you can create a safe, secure, and user-friendly environment.
