We have somewhere around 30;000 lights, but hard to estimate since we use mostly RGB strips (smart and dumb). There are also 3-4 projectors running a projection mapping show synchronized to the light show and window rear projections. There are also inflatables (some large) and a snow machine. The snow machine will run on weekends and on holidays when it's not snowing. Tall inflatables will not run on windy days. We also make some of our own bad animations to use in the projection mappings.
