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 and I_LED = 80mA_DC(LED forward current) until the brightness becomes 50% of its original
value. Operating LED under high temperature environment will reduce life time and lead to color shift.
Note (3) P_L = I_o ×V_o
