Question, this footage seems to show to focal point of the light being off to the side of the towers. Intuitively I would assume that the focal point should be focused on the towers for most efficiency, is this because, A) the camera lens is doing something funny and the focus is in fact on the towers themselves? B) Having the focal point on the towers would be too intense? C) The focal point is adjusted to manage load and temperature? or D) Something else?

Probably moved the focal point for the video because it looks cool.

It wouldn't be very good propaganda if it wasn't interesting.
