Lithonia CPANL 2×4 LED Flat Panel
The CPANL LED Flat Panel provides a uniform, flicker-free light ideal for workspaces and storage areas. Its switchable color temperature lets users tailor lighting to the space, while the high-efficiency LED driver supports long life. It offers damp location suitability and multiple certifications (CSA, IC, DLC). The panel’s long life is supported by rated lumen maintenance above 70% after 60,000 hours, helping reduce maintenance in busy environments. Dimmable operation via compatible Triac dimmers adds energy savings and flexibility.
Lithonia Stack Troffer LED Light
This Stack Troffer fixture emphasizes adjustable lumen output and color temperature for adaptive spaces. The 7-inch lens and curved reflector provide a clean, high-end look with enhanced diffusion and glare control. It supports 0-10V dimming with compatible dimmers and includes an emergency battery backup that ensures up to 90 minutes of operation during power outages. Certifications include CSA, DLC, damp location suitability, and IC rating, delivering reliability in classrooms, offices, and workshops.
Lithonia Frame 2×4 LED Lay-In
The Frame model combines a modern aesthetic with efficient performance. It offers switchable color temperature (3500K, 4000K, 5000K) and adjustable lumen output, enabling precise lighting for different ceiling heights and room types. The design is optimized for weight and cost, delivering similar efficiency to traditional panels but with a lighter footprint. It is suitable for office spaces, classrooms, and other commercial settings that require flexible lighting levels.
SEURON 4 Pack 2×4 LED Flat Panel
SEURON’s 4-pack emphasizes high brightness with 7800 lumens and selectable 5000K color temperature. It uses a 0-10V dimming interface for smooth, flicker-free dimming and a PMMA cover for even light distribution. The fixtures claim an extensive 50,000-hour lifespan, reducing maintenance in high-traffic spaces. They are UL listed and designed for schools, offices, and retail environments, offering energy savings with a straightforward installation process.
ASD 4 Pack 2×4 LED Flat Panel
ASD’s four-pack stands out with selectable color temperatures (3500K/4000K/5000K) and a 5200-lumen output designed for brightness in commercial settings. The panels support 120-277V operation and offer three mounting options: recessed, suspended, or surface mounted (requires additional mounting frame). A robust anti-glare lens reduces eye strain, while the durable housing protects against corrosion and wear for long-term use.
Buying Guide
- Color temperature and lumen output: Choose 3500K–6000K options to match existing lighting and space usage. Higher lumens suit offices and classrooms; warmer temperatures suit breakout areas.
- Dimming compatibility: If you plan to dim, verify 0-10V compatibility and ensure your dimmer is compatible with the fixture model.
- Energy efficiency and life span: Look for DLC, IC, damp-location ratings, and lumen maintenance percentages to minimize future replacements and maintenance.
- Installation options: Recessed vs. surface-mount vs. suspended; ensure mounting hardware or frames are available and compatible with your ceiling grid.
- Emergency backup: For spaces requiring power reliability (hospitals, schools), consider fixtures with built-in emergency battery backup.
- Durability and certifications: CSA, UL, ETL, and IP/damp-location ratings indicate reliability in real-world environments.
- Cost of ownership: While initial costs vary, factor energy savings, maintenance, and replacement cycles over the fixture’s lifetime.
