Notes for Table 4:
1. The standard soak time is the sum of the default value of 24 hours for the semiconductor manufacturer’s
exposure time (MET) between bake and bag and the floor life of maximum time allowed out of the bag at the
end user of distributor’s facility.
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 350
mA. This projection is based on constant current operation with junction temperature
maintained at or below 125°C.
