IllumInatIon luXeon coB core range (Gen 2) Uniform, high-ecffi acy and easy-to-design array The second generation of LUXEON CoB represents a new breakthrough in efficacy for arrays. It has 10% higher efficiency and 10% higher lumen output at the same drive currents as existing LUXEON CoB. Due to its small Light Emitting Surface (LES) and industry-leading thermal resistance, LUXEON CoB is easy to work with, enabling simplified and less expensive luminaire designs. LUXEON CoBs are hot-tested at 85Creal world operating conditionswhich means additional testing can be minimized. LUXEON CoB LEDs are available in 3-step MacAdam ellipse, ensuring uniform optical performance in a wide range of applications. Features and BeneFIts PrImary aPPlIcatIons Highest flux densities with industrys smallest LES Architectural 3-step MacAdam ellipse color definition: Freedom from Binning for color Downlights consistency from luminaire to luminaire Up to 4x lower thermal resistance than competition, enabling smaller heat High Bay & Low Bay sinks and higher lumens Supported by a comprehensive optical, mechanical and electrical ecosystem Lamps Outdoor Specialty Lighting Spotlights No. E352519 DS155 LUXEON CoB Core Range (Gen 2) Product Datasheet 2016 Lumileds Holding B.V.
