CUE considers 15% participation to be the critical mass for a visually impactful Light Show. At this threshold, you'll have enough phones lit up throughout the venue that the effect becomes clearly visible and impressive to everyone in attendance. Because smartphone flashlights are incredibly bright and synchronized, even 15% participation creates a stunning visual effect that reads well both in-person and on camera. Anything above 15% simply amplifies the experience — more phones mean more dramatic visuals, but 15% is where you cross the line from scattered lights to 'wow, that's incredible.'
In practice, CUE typically sees around 22% participation rates with American sports clients and 30-40% internationally with the QR code version. Some events achieve exceptional results — for example, RSC Anderlecht achieved over 70% participation during their first Light Show with a full communication campaign, and approximately 47-48% during their second activation with reduced promotional effort.
Participation rates vary by venue type and context. At concerts, expect 10-20% participation, as some fans prefer to use phones for photos and videos. At halftime shows for soccer matches, account for fans leaving seats for concessions, but 15% still creates an impressive effect. Larger stadiums benefit from the fact that even lower percentages translate to thousands of phones creating a compelling display.
To maximize participation, focus on promotion from the moment fans enter the venue: clear instructions from artists or announcers, adequate time to scan QR codes, visible QR code placement across all sections, pre-show social media promotion, in-app notifications, and countdown timers to build anticipation. The web-based QR code approach has significantly increased participation rates compared to older app-based versions.
