ASD 4ft LED Linear Strip Light Fixture With Emergency Backup
The ASD LSF8 series offers a narrow, low-profile housing suitable for corridors and utility spaces. It features a rust- and impact-resistant commercial-grade enclosure and an anti-glare PMMA lens to reduce eye fatigue in busy work areas. The unit operates on 120-277V with a 0-10V dimmable driver. A built-in battery backup provides 90 minutes of emergency power, ensuring visibility during outages. The fixture supports color and power switching between 3500K, 4000K, and 5000K. It can be linked to other ASD fixtures using a separate connection bracket, enabling scalable light layouts for larger areas.
Walrusled 4 Foot Wraparound Emergency Stairwell Light
This 4-foot wraparound fixture blends performance with practical versatility. It offers two wattages (20W or 40W) and two lumen levels (2500lm or 5000lm) to fit different spaces. The built-in LiFePO4 battery provides emergency power for over 200 minutes, and the unit comes with a touch test switch and indicators. A robust aluminum housing and wide 120-degree beam angle optimize light distribution in stairwells, warehouses, and utility corridors. The fixture is designed for easy installation with multiple mounting options and a clean, low-profile silhouette.
E2 Lighting 4FT LED Linear Shop Light With Emergency Backup
The E2 Lighting fixture provides versatile tunable lighting with five CCT settings ranging from 3000K to 6500K and five wattage options (20W–40W). Each option supports dimming for custom brightness. A built-in emergency battery backup powers the unit for up to 90 minutes during outages, making it suitable for warehouses and garages where outage resilience matters. The design emphasizes energy efficiency, delivering bright illumination while maintaining a balanced power draw in commercial spaces.
ASD 4ft LED Linear Stairwell Strip Light With Motion Sensor
This ASD model emphasizes motion-activated efficiency combined with battery backup. The fixture features a narrow, low-profile form factor with durable housing and an anti-glare lens. It supports 120-277V operation with a 0-10V dimmable driver and offers selectable color temperatures (3500K, 4000K, 5000K). The built-in microwave motion sensor can automatically turn the light off when no motion is detected, reducing energy usage. The 90-minute battery backup ensures continued visibility during outages and shutdowns.
Walrusled 4 Foot Vapor Tight Emergency Light
Designed for outdoor or harsh indoor environments, this Walrusled fixture carries IP65 and IK08 ratings for water, dust, and impact resistance. It includes a built-in LiFePO4 battery backup with a 90-minute to 200-minute runtime, depending on configuration, and a test button for quick checks. With wattage options of 20W (2500lm) and 40W (5000lm), it delivers broad coverage through a 120-degree beam. The fixture’s rugged PC housing and corrosion-resistant components make it suitable for carports, storage facilities, and exposed stairwells.
Buying Guide: Key Purchase Considerations
- Emergency Battery Backup: Check runtime duration (typically 90–200 minutes). Longer runtimes provide more resilience during outages in critical areas.
- Color Temperature Options: Assess color options (3000K–6500K) to match existing ambient lighting and reduce eye strain in workspaces.
- Wattage and Lumens: Compare selectable wattage (20W–40W) and lumen output (2000–5000+ lm) to achieve even coverage across aisles and corridors.
- Motion Sensing: Motion sensors save energy in stairwells and transit areas, but may require calibration to avoid unwanted activation.
- Durability: For damp or outdoor locations, select IP and IK ratings (IP65, IK08) and robust housings to withstand moisture and impact.
- Dimming and Control: Look for 0-10V dimming compatibility and DLC/ETL listing for safety and efficiency.
- Linkable Designs: Linkable fixtures simplify large-area installations by reducing wiring and enabling uniform light distribution across long runs.
- Installation Environment: Consider wet, damp, or dry locations; ensure mounting options align with ceilings, walls, or retrofit schemes.
- Maintenance and Longevity: LED lifespan and ease of maintenance influence total cost of ownership in high-traffic commercial settings.
- Compliance: Verify UL/DLC/ETL listings to meet local building codes and energy standards.
Across these options, the best choice depends on space type, ceiling height, and whether you prioritize motion-activated control, rugged outdoor readiness, or tunable color temperatures. For long corridors and stairwells, a low-profile, high-lumen, battery-backed unit provides reliable performance. In damp or outdoor-adjacent areas, vapor-tight and IP-rated models protect electrical components while maintaining clear visibility during outages. Linkable configurations simplify scaling in larger facilities, ensuring consistent illumination along extended paths.
