>That's why you hear the cooling fans trying to cool them off after the units have been in dynamic mode for a while.

Usually the grid fans are driven by the dynamic braking current itself. This makes them speed up and slow down automatically according to the amount of electrical load through the grids.

The reason you could see the grids glowing was because it was so dark. There was very little incident light from other sources to obscure it.
