LUXEON CoB Core Range – High Density Double the flux in the same form factor LUXEON CoB Core Range – High Density focuses on achieving the highest Center Beam Candle Power (CBCP). With a focus on 6, 9 and 11mm Light Emitting Surfaces, we can cover a flux range as high as 8,000 lumens. Using the mechanical dimensions of our LUXEON CoB Core Range, the High Density range will also benefit from the ability to utilize existing an ecosystem of holders, optics and drivers. Primary Applications Highest flux densities with industry’s smallest LES 3-step MacAdam ellipse color definition: Freedom from Binning for color consistency from luminaire to luminaire Up to 4x lower thermal resistance than competition, enabling smaller heatsinks and higher lumens Track Lights Downlights Supported by a comprehensive optical, mechanical and electrical ecosystem DS189 LUXEON CoB Core Range – High Density Product Datasheet ©2021 Lumileds Holding B.V.
