With the web-based Light Show, you can significantly reduce the lead time compared to the app-based version. Most teams are finding that 90 seconds to 2 minutes is plenty of time for fans to scan the QR code and be ready. Some teams display the QR code throughout pregame on auxiliary screens or pillars, then do a focused 90-second countdown with the code prominently displayed and PA announcements before launching the show. Since there's no app download required, the barrier to entry is dramatically lower and fans can join much faster.
