Notes for Table 3:
1. Total included angle at which 90% of total luminous flux is captured.
2. θ½ is the off axis angle from lamp centerline where the luminous intensity is ½ of the peak value.
3. Tolerance of x, y color coordinates is +/ 0.005.

Notes for Table 4:
1. Dynamic resistance is the inverse of the slope in linear forward voltage model for LEDs.
2. Measured between 25°C ≤ T_J ≤ 110°C at I_F = 1000mA.
