Depending on your age, it might seem like night games have always been a thing at Wrigley Field, the home of the Chicago Cubs--or, you vividly remember the time when there were absolutely no lights, right up to their installation in 1988.
As a kid, I remember asking my dad why he pulled the plug on our Christmas lights at around 9:00 each evening. He said something that came right out of the typical Midwestern dad phrasebook: "What? Am I made of money? Do you know what it costs to run these lights? Do You?"
Let's see if I have this straight. LED (stands for light-emitting diode) lights are 50% more energy efficient than sodium vapor lights, they last 15-20 years instead of 2-5 years, and they spread their illumination far more evenly than standard streetlights.

In case you were unaware, the latest Star Wars movie, "The Force Awakens," opens this Friday. I've got no problem admitting to being a fan, and that I'm really looking forward to seeing it...
