Notes for Table 7:

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, LED Engin projects that the LZ Series will deliver, on average, 70% Lumen

Maintenance at 65,000 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.
