There will be more in a slideshow at nhregister.com later tonight, but here's a sneak peek with one of the four light towers up at the Bowl. The light towers each have 15 6,000 watt bulbs.

If you click on photos they will appear full size on your screen.

Catherine Avalone-New Haven Register 

Lighting technicians from Musco Lighting from Oskaloosa, Iowa, adjust one of four portable lighting trucks, Thursday, November 19, 2015, each containing fifteen individual lights producing six thousands watts to illuminate the Yale Bowl for Saturday's game against Harvard. The lighting is a first in the history of the Bulldog's football program.

This is with two banks of lights illuminated.

Photographer stated each of the lights was adjusted hundreds of times as the engineers walked around the field with light meters. Walkie talkies were used to communicate with those adjusting each of the bulbs.
