How Many Lumens Do I Need for Parking Lot Lighting?
Share
Introduction
Proper lumen output ensures safety, visibility, and cost savings for commercial parking lots. Too little light causes accidents; too much wastes energy.
Calculating Lumen Requirements
- Small lots (≤10 cars): 5,000–10,000 lumens
- Medium lots (10–50 cars): 10,000–20,000 lumens
- Large lots (>50 cars): 20,000–40,000 lumens
Factors Affecting Light Levels
- Mounting height
- Light spacing
- Fixture efficiency (LED vs traditional)
Recommended LED Fixtures
- 100W–150W LED shoebox lights for medium lots
- 200W–300W for large areas
FAQ
Q1: Does color temperature matter?
Yes, 5000K daylight is best for parking lots.
Q2: Can I reduce energy with LEDs?
Yes, LED retrofits can save 60–75% energy.
