LED Highway Lighting

What are LED Highway Fixtures?

LED highway roadway lighting includes illumination systems for overpasses, underpasses, interchanges, exits, and merge lanes. Modern LED street lighting fixtures improve nighttime driving safety, offer energy efficiency, and provide long-term reliability. With 15+ years working with highway authorities and transportation departments, we have seen that proper LED highway lighting reduces accidents and creates safer travel conditions for millions of drivers.

What are the Different Types of LED Highway Lighting We Offer?

Highway applications require specialized fixtures for high-performance roadway environments. LED street lights are used for standard roadway sections, while LED high mast lights cover complex multi-lane intersections. Pedestrians use dedicated walkway fixtures, and LED cobra head lights provide traditional pole-mounted illumination. Overpass installations require specialized mounting solutions. LED Lighting Supply designs interchange high mast lighting solutions for uniform light distribution across multiple traffic lanes.

What are the Best LED Lighting Supply Options for:

Highway Underpass: LED wall packs rated at 50-150 watts or LED canopy lights with 100-300 watt output are recommended for underpasses. Mounting height and required footcandle levels determine the best fixture.

Highway Construction: LED flood lights delivering 20,000+ lumens provide focused illumination for work zones. Portable and permanent mounting options are available for different project phases.

Highway Overpass: Pole-mounted streetlights with Type II or Type III distributions are ideal for elevated roadways.

Highway LED Tunnel Lighting: Wall-mounted or ceiling-mounted linear fixtures with IP65 ratings handle vehicle exhaust and moisture. These lights also require ventilation considerations and corrosion-resistant housings.

What are Recommended Foot Candle Readings for Highways, Freeways, and Interchanges?

• High-Traffic Highways & Freeways: 0.6 to 2.0 footcandles for adequate visibility during high-speed travel
• Interchanges and Ramps: 1.0 to 2.5 footcandles for complex merging and directional changes
• Underpasses: 1.5 to 3.0 footcandles to offset reduced ambient light
• Tunnels: 2.0 to 5.0 footcandles for safe navigation in enclosed sections

Installation and Voltage Compatibility

Highway LED street light fixtures support 120V to 480V input. Built-in drivers adjust to existing voltage without extra transformers or rewiring. Most installations use 277V or 480V three-phase power for efficiency. We recommend professional photometric analysis during planning to ensure fixture spacing and mounting heights meet IESNA RP-8 standards for roadway lighting.

Dimming and Smart Controls

Advanced highway LED systems integrate with traffic management networks using 0-10V dimming protocols and wireless controls. Adaptive lighting increases illumination during peak hours and reduces output during low-traffic periods. Smart sensors can detect vehicles and weather, automatically adjusting light levels for safety and energy savings. A dawn-to-dusk photocell feature can provide an additional 20-30 percent energy savings beyond standard LED efficiency.

Safety and Performance Certifications

All our fixtures carry essential certifications, including DLC Premium for energy efficiency and rebate eligibility, UL Listed for electrical safety, and ETL Listed for product safety compliance. These certifications help ensure safety, performance, and energy efficiency, and may qualify your project for utility rebates and tax incentives.

Warranty and Support

All our lights include at least a 5-year warranty, with USA-based support. Our team is committed to resolving warranty claims quickly to keep your lighting operational.

Benefits of LED Lights for Freeways, Interchanges, and Highways

• Enhanced Visibility: Advanced optics reduce dark spots and provide uniform illumination across traffic lanes. Drivers benefit from improved depth perception and hazard recognition without excessive glare.
• Longevity and Durability: Highway-grade LED fixtures operate reliably for 50,000+ hours, depending on model, or over 11 years of continuous use. Robust construction withstands temperature extremes, road salt, and vibration from heavy traffic, making them suitable for harsh weather.
• Energy Efficiency: Modern LED systems reduce energy use by 60-70 percent, subject to site conditions, compared to metal halide. A 400W metal halide replacement typically requires only 150W LED power for similar output.
• Reduced Maintenance Costs: Solid-state LED technology eliminates frequent maintenance for lamp and ballast replacements. Highway departments save on labor and equipment with virtually maintenance-free operation.
• Instant On: LEDs reach full brightness immediately, unlike HPS fixtures that need warm-up time. This is critical for emergency and security lighting.
• Improved Light Quality: High CRI ratings above 70 enable better color recognition and hazard identification (verify on spec sheet). Drivers can more easily distinguish road markings, signs, and obstacles compared to sodium lighting.
• Reduced Light Pollution: Precision optics direct light where needed, minimizing sky glow and light trespass. This meets IES roadway standards and reduces impact on surrounding areas and the night sky.
