The Zoo Lights event was enjoyable and worth the price of admission (you can also find discounted tickets on Groupon).
Be sure to check out the Splash of Color (water and laser, light show), it only lasts a few minutes and is quite the specatcle.
The only downside is actually getting in to the zoo itself. We had tickets for the 6:00pm time slot and arrived right at 6:00pm. However, then you have to get in a line that winds back and forth through the parking lot and we didn't get into the zoo until about 6:30pm. We still had plenty of time to see everything, but this is a popular event, so arrive a little early.
