35、e of any light assembly to meet the limits specified in MIL-STD-461 (see 3.4.8) shall constitute a test failure. 4.4.2 Cold starting test at 60 Hz. Each of the light assemblies from the sample light set shall be cold soaked for 4 hours at a temperature of 0F. While maintaining a temperature of 0F, a
36、n electric power of 120 + 5 volts, 60 Hz shall be applied to each light assembly and the light operated for a minimum of 1 hour.
