LED Semi Cutoff Wall Packs

What are Semi-cutoff LED Wall Pack Lights?

Semi-cutoff LED wall pack lights deliver balanced outdoor illumination that bridges the gap between full cutoff and wide-throw fixtures. These fixtures mount directly to building exteriors and distribute light both downward and outward in equal measure, creating 120-degree beam patterns that cover substantial ground area while controlling upward light spill. The controlled distribution makes them particularly effective for building perimeters, walkways, and parking zones where you need security coverage without excessive glare or light trespass onto neighboring properties.

How to Determine Semi-Cutoff LED Wall Pack Lighting is the Best Choice

Choosing semi-cutoff fixtures requires evaluating your specific lighting objectives and site conditions. We typically recommend these when customers need broader coverage than full cutoff provides but still want reasonable dark-sky consideration. Your mounting height directly influences effectiveness—installations between 12-20 feet optimize the balanced light throw these fixtures are designed to deliver.

• Coverage requirements: Semi-cutoff patterns work best when illuminating areas 25-40 feet from the building face while maintaining adequate vertical illumination on the wall surface itself.
• Existing infrastructure: Most customers upgrading from 150W to 400W metal halide or high-pressure sodium can achieve equal or better performance with 30W to 80W LED semi-cutoff replacements.
• Municipal compliance: Where full cutoff isn't mandated but light pollution concerns exist, semi-cutoff fixtures reduce upward light emission by approximately 60% compared to traditional wall packs.
• Multi-zone applications: Properties requiring both pedestrian-scale lighting and broader security coverage benefit from the versatile distribution pattern.

Beyond photometric considerations, factor in your preferred color temperature (3000K to 5000K), dimming requirements, and sensor integration needs. Our lighting design team creates comprehensive photometric plans that eliminate guesswork in fixture selection and spacing.

Benefits of LED Semi Cutoff Wall Pack Lights

Upgrading to LED semi-cutoff wall packs delivers measurable improvements across multiple performance categories compared to legacy HID systems:

• Immediate Energy Reduction: Achieve 70-80% energy savings with superior light quality. A typical 50W LED replacement outperforms a 250W metal halide while reducing monthly operating costs by hundreds of dollars on multi-fixture installations.
• Extended Service Life: Rated for 50,000+ hour operation with less than 10% lumen depreciation over five years. This eliminates the frequent lamp replacements and ballast failures common with HID technology.
• Reliable Cold Weather Performance: Unlike HID lamps that struggle in low temperatures, LED drivers maintain consistent output down to -40°F without warm-up delays or reduced efficiency.
• Smart Integration Ready: Factory-installed 0-10V dimming and occupancy sensors enable automated operation that further reduces energy consumption during low-activity periods.

How to Calculate How Many Semi-Cutoff Wall Pack Lights You Need

Proper fixture quantity depends on achieving uniform illumination levels across your target area. Based on our experience with thousands of installations, most commercial properties require wall pack spacing between 40-60 feet to maintain adequate light levels without creating bright spots or shadows.

We approach every project with professional photometric analysis that considers building dimensions, mounting heights, adjacent structures, and required foot-candle levels. This eliminates costly over-lighting or inadequate coverage issues. Our lighting plans include precise fixture locations, wattages, and beam angles tailored to your specific site conditions and usage requirements.

Dark Sky Compliant Semi-Cutoff Wall Packs

Our semi-cutoff wall pack fixtures significantly reduce light pollution while maintaining effective ground-level illumination. The controlled optical design limits upward light emission to less than 5% of total fixture output, helping properties meet many municipal dark-sky ordinances without sacrificing security or visibility.

For areas with stricter full cutoff requirements, we offer complete cutoff wall packs with zero upward light emission. These fixtures concentrate 100% of their output below horizontal, providing maximum dark-sky compliance for sensitive locations near airports, observatories, or environmentally protected zones.

Installing Semi Cutoff LED Wall Pack Lights

Professional installation typically requires 30-45 minutes per fixture for direct retrofits. After disconnecting power and removing existing hardware, the new LED wall pack mounts using the included bracket system designed for standard electrical box configurations. Most models accept 120V to 277V input with drivers that automatically adjust to your building's electrical system.

Wire connections follow standard practices—line, neutral, and ground—with many fixtures including integral junction boxes that simplify the process. For installations requiring photocells or occupancy sensors, we recommend discussing placement and wiring requirements with your electrician during the planning phase to ensure optimal sensor performance.

Safety and Performance Certifications

All our fixtures carry essential certifications including DLC Premium, UL Listed, and ETL Listed approvals. These certifications ensure safety, performance, and energy efficiency while qualifying your project for utility rebates and tax incentives. DLC Premium certification guarantees the highest efficiency standards and maximum rebate eligibility.

Warranty and Warranty Support

All our lights come with at least a 5-year warranty, and all warranty support is based in the USA. We take customer support seriously, and helping you with a warranty claim is important to us. Our experienced support team understands the importance of keeping your lighting operational and will work quickly to resolve any warranty issues.
