*1:The number of LED kinds
*2:AP is the hybrid driving of AM and PWM. The frequency of PWM is from 0.1 Hz to 1000 Hz.
*3:Actually 1000 steps can be used because some steps for low luminance calibration.
*4:Light quality is measured with 80% power
*5:When set light source as D50 without warm up time under enviroment temperature 25°, short-term stability is measured during 24 hours and compared to average value.
*6:When set light source as D50 after 30 minutes warm up time under enviroment temperature 25°, long-term stability is measured during 90 days and compared to average value.
*7:Users can utilize the SDK to realized the functions of Dynamic lighting, Single channel control.
*8:Users need to have the compatible instrument for measurements
