Direct PWM (low) frequency should be selected such to not have optical interference.
Lamp current is specified with NEC NL12876BC26-25 and all 4 lamps connected with frame of panel grounded.
n is lamp number CN1
At room temp, 1 hour full brightness operation and 1 hour full dim operation measurement ratio.
