Description
The LZ4-00CW10 Cool White LED emitter provides 10W power in an extremely small package.
With a 7.0mm x 7.0mm x 4.3mm ultra-small footprint, this package provides exceptional
luminous flux density. LedEngin’s patent-pending thermally insulated phosphor layer provides
spatial color uniformity across the radiation pattern and a consistent CCT over time and
temperature. LedEngin’s LZ4-00CW10 LED offers ultimate design flexibility with individually
addressable die. The high quality materials used in the package are chosen to optimize light
output and minimize stresses which results in monumental reliability and lumen maintenance.
The robust product design thrives in outdoor applications with high ambient temperatures and
high humidity.

Average Lumen Maintenance Projections
Lumen maintenance generally describes the ability of a lamp to retain its output over time. The
useful lifetime for solid state lighting devices (Power LEDs) is also defined as Lumen
Maintenance, with the percentage of the original light output remaining at a defined time period.
Based on long-term WHTOL testing, LedEngin projects that the LZ Series will deliver, on
average, 90% Lumen Maintenance at 100,000 hours of operation at a forward current of
700 mA per die. This projection is based on constant current operation with junction
temperature maintained at or below 125°C.
