International Shipping Port Upgrades to LEP

Case Study: International Shipping Port
Application: High Mast Lighting

The constant activity at a commercial shipping port puts a high demand on the quality and reliability of its lighting infrastructure, requiring bright light to be distributed over a vast area for safety at any time of day or night.

Goals

• Improve energy efficiency by replacing 1000W HPS lighting system
• Centralize wireless controls (on for 12 hrs/day, dimmed for 6-8 hrs/day)
• Install safer and higher quality lighting across 100 high mast poles

Highlights

• 75% energy savings with Light Emitting Plasma and wireless dimming controls
• Higher visibility levels with more accurate color rendering
• 2 fewer fixtures per pole reducing pole weight by 80lbs
• Minimized maintenance at 100ft heights above ground
