1. Ireg(SS) steady state is the voltage (Vak) applied for a time duration ≥ 10 sec, using FR−4 @ 300 mm2 1 oz. Copper traces, in still air.

2. Voverhead = Vin − VLEDs. Voverhead is typical value for 85% Ireg(SS).

3. Ireg(P) non−repetitive pulse test. Pulse width t ≤ 300 msec.

4. f = 1 MHz, 0.02 V RMS.
