Cree XLamp CXA2540 4000K LED CXA2540-0000-000N0UU240G High-Density UU Bin COB Array for Industrial Lighting

Product Details

     Cree XLamp CXA2540 4000K LED CXA2540-0000-000N0UU240G High-Density UU Bin COB Array for Industrial Lighting. The Cree XLamp CXA2540 is a high-flux, multi-die integrated array designed specifically for manufacturers who require intense lumen density and industrial-grade reliability in a standardized footprint. The CXA2540-0000-000N0UU240G provides a professional 4000K neutral-white output, binned at the UU flux level. Operating on a 36V platform, this COB (Chip-on-Board) is engineered to deliver maximum lumens-per-watt, making it the preferred light engine for high-bay fixtures, outdoor area modules, and commercial downlights where system-level cost reduction is a primary objective.
 

     For LED module manufacturers and fixture designers, the 19mm Light Emitting Surface (LES) of the CXA2540 offers a tactical advantage in optical design. Its ability to produce over 4200 lumens from a single optical source allows luminaire manufacturers to utilize more compact secondary optics and streamlined heat sink designs compared to traditional multi-die SMD arrays, effectively lowering the overall Bill of Materials (BOM).

Critical Engineering Advantages

- Integrated Hot-Color Targeting: Unlike standard LEDs that shift color at high temperatures, Cree characteristically bins the CXA2540 at 85°C. This ensures that the 4000K chromaticity and UU flux tier reflect real-world operating temperatures, eliminating the "color-shift" guesswork for R&D engineers.

- Exceptional Thermal Management: Built on a robust ceramic substrate with an ultra-low thermal resistance of only 0.30 °C/W, the CXA2540 facilitates rapid heat transfer. This stability protects the L70/L90 lifespan, a critical requirement for municipal and commercial contracts.

- 3-Step MacAdam Binning (40G): Utilizing Cree's EasyWhite® technology, this SKU provides tight color consistency, ensuring that variance between individual fixtures is virtually invisible to the human eye-even in large-scale office or retail installations.

- High Center-Beam Candlepower (CBCP): The 19mm LES is compatible with a wide array of off-the-shelf reflectors and TIR lenses, facilitating tight beam angles and superior light throw, which are essential for high-clearance manufacturing floors.

The CXA2540-0000-000N0UU240G is widely integrated into performance-heavy fixtures:

- Industrial High-Bay & Low-Bay: Consistent, high-efficacy neutral white light for warehouses requiring 50,000+ hour lifespans.

- Commercial Downlights: Professional-grade Recessed modules for lobbies and showrooms where 4000K balance is required.

- Outdoor Area Lighting: Durable COB source for parking lot wall packs and security floodlights.

- Track Spotlights: Ideal for high-end retail displays where tight beam control and color uniformity across large batches are mandatory.
