Description
The LZ1-00WW03 White LED emitter provides 3W power in an extremely small package. With
a 4.4mm x 4.4mm x 3.2mm ultra-small footprint, this package provides exceptional luminous
flux density, up to 5 times greater than competitors’ equivalent 3W products. LedEngin’s patent-
pending thermally insulated phosphor layer provides a spatially uniform color across the
radiation pattern and a consistent CCT, CRI 85 and R9 30 over time and temperature. 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. This projection is based on constant current operation with junction temperature
maintained at or below 125°C.
