Lumileds LUXEON HL2Z 4000K LED High-Density Un-domed Emitter L1HZ-4070200000000

Product Details

Lumileds LUXEON HL2Z 4000K LED High-Density Un-domed Emitter L1HZ-4070200000000. The Lumileds LUXEON HL2Z is a state-of-the-art, high-power un-domed LED designed for manufacturers who require intense radiant flux density and precise beam control in a compact form factor. Specifically, the L1HZ-4070200000000 provides a neutral 4000K output with a minimum CRI of 70. Built on a specialized 2.3 mm x 2.3 mm footprint, this emitter bridges the gap between traditional 3535 LEDs and chip-scale packages (CSP), offering LED module manufacturers the optical density of a CSP with the mechanical reliability and ease of assembly found in standard high-power components.

For luminaire designers focusing on roadway and industrial lighting, the LUXEON HL2Z provides a tactical advantage in optical etendue. Its small Light Emitting Surface (LES) and low-profile height facilitate superior coupling efficiency with secondary TIR lenses and reflectors, enabling much higher center-beam candlepower (CBCP) than standard domed LEDs.

Critical Engineering Advantages for B2B Buyers

• Extreme Optical Etendue Control: The flat-top, un-domed construction minimizes the source size. For fixture manufacturers, this facilitates tighter beam angles and maximum "light-on-target" efficiency, reducing spill light in roadway and high-mast installations.
• Maximized Lumen Density: The HL2Z handles massive drive currents up to 2.0A. This high-density output allows engineers to achieve target lumen packages with fewer LEDs, effectively lowering the overall Bill of Materials (BOM) and reducing the size of the required heatsink.
• Superior Thermal Path Reliability: Built with a direct thermal path architecture, the L1HZ series ensures efficient heat transfer from the junction to the PCB. This stability protects the InGaN chip during continuous high-current operation, preserving the L70/L90 lifespan required for municipal tenders.
• Verified Reliability at 85 °C: Lumileds characteristically bins the HL2Z at 85 °C, ensuring that the 4000K chromaticity and flux performance match real-world operating conditions once the lamp reaches thermal equilibrium on-site.

The L1HZ-4070200000000 is a staple component for performance-driven markets:

• Roadway & Street Lighting: High-efficacy neutral white source for municipal infrastructure projects requiring precise light distribution and energy labels like DLC® Premium.
• Industrial High-Bay & Low-Bay: Consistent, high-intensity emitters for warehouse and factory environments where daylight contrast is essential for safety.
• Specialty Spotlights & Searchlights: The small LES allows for extreme optical throw (cd/lm) when paired with narrow-angle parabolic reflectors or specialized TIR optics.
• Architectural Facade Lighting: High-density arrays for facade grazing where fixture weight and wind-load must be minimized without sacrificing radiant power.
