Yellow squares indicate typical operating conditions.
Mean expected lifetime in dependence of junction temperature at 0.35 A/mm
70% of initial intensity. Based on lifetime test data of uncoated GaN devices at this time. Data can be used to model failure rate over
typical product lifetime.
Lumen maintenance in dependence of time at 0.35 A/mm
