Cree CXB1520 High Density (HD) LeD

arrays are the next generation of high

lumen density LeD arrays. Incorporating

elements of Cree’s SC5 Technology™

Platform, the CXB1520 HD LeD arrays

deliver the most lumens in the industry

for their light-emitting surface (LeS)

size,

enabling

radically

new

and

differentiated LeD lighting form factors

for applications like tracks, lamps and

downlights. The CXB1520 HD LeD

array packs the performance of seven

60-watt-replacement lamps in an area

significantly smaller than a dime, allowing

lighting manufacturers to put more light

where it is intended at a lower system

cost.

The CX Family LeD Design Guide provides

basic information on the requirements

to use the CXB1520 HD LeD array

successfully in luminaire designs.
