DRONE LIGHT SHOWS:
Show Costs: (Reusable)
Between $ 10,000 to 1 million + depending on number of drones, duration, visuals and company.
Shows last around 8-12 minutes (for now)
Max. drones: 2,018 in Folsom, California. 5 minutes. (Intel Shooting Stars) * (Need Update)
I believe drone light show costs will lower over the years.
