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. n/a n/a 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, 7% Lumen Maintenance at 65, hours of operation at a forward current of 7 ma. This projection is based on constant current operation with junction temperature maintained at or below 125 C. 5
