The power level was defined by the amount of heat that could be shed operating at 100% continuous duty under worst case conditions - which would be parked, idling, on a hot desert night, so no airflow in an ambient temperature of 100°F / 37.8°C.
Commercially available light bars cannot do this, their heat sinks are much too small …
