- Installation Flexibility: Ensure the fixture supports drop ceilings, surface mounting, or suspension. Verify whether mounting kits are included or sold separately.
- Certification and Durability: DLC and UL listings signal reliability; damp location ratings matter for certain environments (e.g., restrooms, kitchens).
- Maintenance and Diagnostics: Built-in test buttons and status indicators streamline maintenance checks and ensure readiness during outages.
- Power and Compatibility: Many panels operate at 100–277V with universal drivers, simplifying retrofits in existing buildings.
- Design and Aesthetics: Consider lens design, glare control, and diffuser quality for comfortable, uniform lighting across workspaces.
