1. I_reg(SS) steady state is the voltage (Vak) applied for a time duration ≥ 300 sec, using 900 mm² DENKA K1, 1.5 mm Al, 2kV Thermally
conductive dielectric, 2 oz. Cu (or equivalent), in still air.
2. V_overhead = V_in − V_LEDs. V_overhead is typical value for 70% I_reg(SS).
3. I_reg(P) non−repetitive pulse test. Pulse width t ≤ 360 msec.
