Note (1) LED current is measured by utilizing a high frequency current meter as shown below:
Note (2) The lifetime of LED is defined as the time when it continues to operate under the conditions at
Ta = 25 ±2 к and Duty 100% until the brightness becomes 50% of its original value.Љ
Operating LED at high temperature condition will reduce life time and lead to color shift.
