Buying Guide
What to consider when choosing 2×4 lay-in fixtures:
- Brightness and lumen output: Larger rooms or spaces with high ceilings benefit from higher lumens (e.g., 7000–7800 lm).
- Color temperature: Switchable or selectable CCT options (3000K–6500K) help tailor mood and visibility for tasks.
- Dimming capability: 0-10V dimming and compatible controls reduce energy use and create comfortable lighting levels.
- Ceiling compatibility: Some panels are designed for drop ceilings, others work with suspensions; check depth, driver access, and mounting brackets.
- Durability and ratings: Damp or ETL/DLC certifications improve reliability in commercial environments and reduce maintenance concerns.
- Installation scale: Bulk packs lower per-unit costs but require planning for wiring, control systems, and space layout.
