Boost Retrofit Speed, Energy Savings with the Metalux CBRK LED Center Basket Kit
The Metalux CBRK Center Basket Retrofit Kit from Cooper Lighting has become a go‑to option for contractors who want a clean, efficient upgrade path without the hassle of replacing entire troffers. Designed to fit standard 1×4, 2×2, and 2×4 fluorescent housings, it delivers a modern center‑basket aesthetic with noticeably improved optical performance.
The CBRK’s custom diffuser produces smooth, low‑glare illumination that immediately elevates older commercial spaces, while its field‑selectable lumen output allows on-site adjustments to match existing light levels or meet new design requirements. Output ranges typically fall between 2,100–4,700 lumens for 2×2 models and 4,300–7,300 lumens for 2×4 models, with 3,500K and 4,000K color temperatures available at 80 CRI.

Installation and Performance Advantages for Retrofits
The CBRK is engineered for fast, low‑disruption retrofits. Its tool‑less installation method allows the kit to slide into the existing housing and lock into place without brackets or extensive teardown. This is especially valuable in occupied buildings where downtime needs to be minimal.
A tool‑less installation directly translates into saved labor, fewer job‑site complications, and smoother project execution. Specifically it:
- Cuts installation time dramatically, allowing crews to complete more fixtures per hour and reduce overall project duration.
- Lowers labor costs by minimizing the hands‑on time required for each retrofit, especially valuable on large commercial jobs.
- Reduces the need for specialized tools, which helps avoid delays caused by missing equipment or shared tool bottlenecks on busy sites.
- Decreases the risk of installation errors, since fewer components and steps mean fewer opportunities for mistakes or rework.
- Simplifies training for new installers, making it easier to scale crews or bring in additional labor during peak periods.
- Reduces cleanup time, with no screws, brackets, or debris left behind.
- Supports tight project schedules, especially in retrofit environments where access windows are limited.
In addition, the galvanized steel housing adds durability, and the low‑profile design ensures compatibility with standard grid ceilings. Controls integration is also well thought out, with standard 0–10V dimming and compatibility with WaveLinx LITE and WaveLinx PRO systems for projects requiring advanced energy‑code compliance.
