FONZ doesn't have to do with this.

This is an event run by the Zoo.

I mean, so is putting up the lights.

The largest problem was that it was causing issues for the animals. Especially the animal houses being open.

They bought new lights to replace the old ones. Because the old ones were problematic for animals.

I also have a source. It's because of the animals.

Why would they spend thousands of dollars on brand new lights instead of simply using the ones they already had?

Nah. It has to do with them trying to minimize impact to the animals. Bright lights at night, tons of visitors, and indoor areas being lit and trafficked when animals are trying to sleep can be distressing to animals.

Some of the exhibits used to be open, but they changed that because having guests in the exhibits at night was messing with the animals' well-being.

I also know that they stopped using a certain type of light and instead did another type of light (not sure of which specific lights). Again, due to the previous ones causing problems for the animals' well-being.

The Zoo is trying to basically do what they can to make it enjoyable without compromising their primary goal: preserving the well-being of their animals.

It might be a bit disappointing for visitors, but I'm glad they're prioritizing the zoo animals, personally.
