A Full Lighting Analysis and Photometric Breakdown
Upgrading exterior lighting is one of the most effective ways to improve safety, visibility, and energy efficiency in commercial properties. River Hills Mall required a complete assessment of its exterior parking lot lighting due to aging fixtures and uneven coverage across the property. This report reviews the lighting conditions, the photometric study results, the selected LED replacement fixtures, and the benefits the property will gain from the upgrade.
Project Overview
River Hills Mall is a large retail property with multiple parking zones, pedestrian walkways, and perimeter traffic routes. The existing lighting system showed significant dark areas, outdated optics, and inconsistent light levels across the parking lot.
The goal of this project was to design a lighting layout that delivers:
-
Higher light levels for improved visibility
-
Consistent illumination with smooth transitions between poles
-
Better uniformity ratios for increased safety
-
Lower energy usage through modern LED technology
-
Reduced maintenance and long term reliability
Existing Site Conditions
The mall incorporates several wide open parking fields along with perimeter lanes, loading areas, and pedestrian paths. Many of the legacy fixtures no longer provided adequate illumination, creating areas of visual discomfort and low visibility during evening hours.
Photometric Analysis
A full lighting simulation was completed to ensure the updated design meets recommended parking lot lighting standards. The following renderings show the projected light distribution across the property.

Angled Photometric Views
The lighting summary provides a breakdown of the fixtures used and their performance across the site. Two fixture configurations were analyzed:
-
UPK1 300W 5000K
-
UPK1 300W 5000K with Backlight Control (BB)
Both fixtures produce 44,723 lumens each and were placed strategically across the lot to create consistent illumination.
The final results show strong performance in key areas:
-
Academy Parking Average: 4.11 foot-candles
-
Main Parking Lot Average: 1.57 foot-candles
These averages fall within recommended industry standards for general parking lot lighting and provide balanced visibility without excessive glare.
The combination of high output and controlled optics ensures that the brightest areas are directed toward high traffic zones while maintaining even lighting across the full property.
LED Area Light for Parking Lots and Roadways
This fixture offers strong forward throw and wide distribution patterns ideal for large properties. Key benefits include:
-
High performance LED output
-
Advanced optics for precise site lighting
-
Long life rating for reduced maintenance
-
Significant energy reduction compared to older HID systems
The fixture was paired with proper mounting heights and optics to achieve the optimal light spread shown in the photometric analysis.
Final Notes
The full lighting redesign for River Hills Mall greatly improves nighttime visibility, enhances visitor safety, and lowers long term operational costs. The new LED fixtures deliver strong, dependable illumination while significantly reducing power consumption.
