The Xenon light was clearly superior.
The 3D-Coverage values are evidence that the Xenon technology offers a wider range and is more readily perceived.
The reason for this is that the Xenon flashing light emits a very short but intense pulse with a peak value far exceeding 100,000 cd. The light pulse of an LED flashing light is longer, but only reaches around 400 cd.
Furthermore, because the Xenon gas is energised in a glass tube, the light signal is emitted evenly in all directions. Conversely, the linear nature of LED light relies on reflectors and optical lenses to create an omnidirectional profile.
