Total included angle at which 90% of total luminous flux is captured.
θ½ is the off axis angle from lamp centerline where the luminous intensity is ½ of the peak value.
Tolerance of x, y color coordinates is +/ 0.005.
Dynamic resistance is the inverse of the slope in linear forward voltage model for LEDs.
