The HV differential would accelerate the photons (light coming in), striking the loop and illuminating it. The rate of acceleration is the light amplification factor, this one was about 2-4 times normal, which meant that they could see us before we could see them. Night vision of today is the same concept, but is now up to more than 100,000 times.
