FlipToLed 2×4 Emergency Panel With Backup
The FlipToLed 2×4 panel combines high lumen output with a built-in battery that supports up to 120 minutes of emergency illumination. It features three selectable color temperatures (3000K/4000K/5000K) and a 0-10V dimming range from 100% to 10%, enabling precise brightness control for classrooms, offices, or retail spaces. Installation is versatile: drop-in ceiling, surface mounting, or suspension can be used with appropriate kits. The indicator screen provides color-coded status cues and a test button ensures ongoing readiness.
2X4 LED Flat Panel With Emergency Backup (2 Pack)
This two-pack set from LED ENERGY PLUS delivers 6960 lumens, roughly 116 lm/W, and supports dimming from 100% to 10%. It includes a built-in emergency battery backup with up to 120 minutes of run time, and an indicator screen to monitor status. Flexible installation options include standard drop ceiling integration, surface mounting with a kit, or suspension mounting with a kit (kits sold separately). The product is DLC and UL listed, making it a reliable option for commercial installations that require code compliance.
Lithonia 2×4 LED Troffer With Emergency Backup
The Lithonia 2×4 Troffer features a switchable color temperature range (3500K/4000K/5000K) and an adjustable lumen output, along with an integrated 90-minute emergency battery backup. The fixture is designed with glare-reducing diffusion and a wide lens for even illumination. It is CSA certified, DLC qualified, and suitable for damp locations. Its 0-10V dimming compatibility supports compatible dimmer systems, offering flexible control for various spaces such as garages, classrooms, and offices.
2X4 LED Flat Panel With Backup (1 Pack)
This single-panel option provides 6960 lumens with an efficiency around 116 lm/W and 120 minutes of emergency power. It supports 100% to 10% dimming and offers flexible installation options for drop ceilings, surface mounting, or suspension mounting (kits sold separately). An indicator screen communicates battery status via color indicators, and a test button simplifies routine checks, helping facilities maintain readiness during outages.
FlipToLed 2X4 LED Panel With Backup (2 Pack)
This 2-pack mirrors the single-pack design with 120 minutes of battery backup, three color temperature options, and high-efficiency output at 6960 lumens. It preserves 0-10V dimming and offers flexible mounting options, including drop-ceiling integration, surface mounting, or suspension, though mounting kits are not included. The installer-friendly features support rapid deployment across multiple rooms or zones.
VocgoUU 4 Pack 2×2 LED Panels (Emergency Backup)
Although this option is a 2×2 format, it showcases emergency backup features and UL/ETL listings that reflect the same safety mindset as 2×4 models. It offers 90+ minutes of battery life on standby, three color temperatures, and UL-listed emergency drivers with multiple protections. This makes it a practical alternative for smaller spaces or retrofit projects where a 2×2 footprint fits better while still delivering reliable emergency illumination.
Buying Guide: Key Purchase Considerations
When choosing a 2×4 emergency light fixture, consider the following factors to ensure the best fit for your space and safety requirements:
- Emergency runtime: Typical panels offer 90–120 minutes. Verify run time aligns with local codes and expected outage durations in your area.
- Color temperature: Options usually range from warm 3000K to cool 5000K. Select based on room usage and occupant comfort; offices often favor 3500K–4000K blend for clarity without harshness.
- Dimming and control: 0-10V dimming enables fine brightness control. Check compatibility with existing dimming infrastructure and wiring.
- Installation flexibility: Drop ceilings, surface mounting, and suspension mounting broaden placement possibilities. Confirm kit availability and any additional costs for mounting hardware.
- Lumens and efficiency: Higher lumens improve visibility, but ensure the fixture’s output suits the ceiling height and room size. Efficiency (lm/W) reflects energy use and operating costs over time.
- Emergency indicators: A clear status display and test button simplify maintenance and compliance checks. Consider maintenance practices and how easily staff can verify readiness.
- Certifications and compatibility: DLC, UL, ETL, and damp-location ratings indicate safety and reliability. Ensure compliance with local electrical codes for commercial spaces.
- Warranty and service: Longer warranties reduce lifecycle risk. Check what is covered and whether there are service options for battery replacement.
In practice, choose a model that balances emergency runtime, color temperature flexibility, and installation versatility. For larger or multi-room deployments, a two-pack or four-pack option may reduce procurement complexity and ensure consistent lighting across zones. Consider aligning with existing ceiling systems and dimming infrastructure to minimize retrofitting costs and downtime.
