How it differs from other light shows
- LED-costume performers: a 5–10 minute act, the audience watches from their seats, from 25,000 ₽
- Laser and neon shows: equipment rental, rigging, a fully dark room required
- GROMKA.SHOW: the whole room takes part, nothing to rig, from 10,000 ₽. The formats mix well: our show often closes the night after the performers’ act

- Do guests need to install an app?
- No. Scan the QR code and open the page in a browser. Works on iPhone and Android
- Will it ruin the formal atmosphere at a wedding?
- The format fits your script: soft glow for the dance or a bright finale. The show starts from the sound desk at exactly the right moment
- What does the venue need to provide?
- A QR code on screen or print, sound for ultrasonic sync (speakers or desk), internet for the first page load
- Who launches the show?
- The sound engineer, DJ or host – anyone with access to the sound. We prepare the script and control tracks in advance
- How much does a light show cost?
- From 10,000 ₽ for a room of up to 100 guests, a fixed price for the whole event. For comparison: an LED-costume act starts at 25,000 ₽, a drone show at 500,000 ₽. Get a quote for your audience on the pricing page
- How is it different from an LED-costume performance?
- With performers the audience watches the act; with us the audience is the show: every guest with a phone becomes a pixel of the shared picture. The formats don’t compete: a performers’ act can open the night, and our show can bring everyone together in the finale
- Does it work for a New Year corporate party or a prom?
- Yes, these are the most common scenarios: a dark room, the highlight of the night, every guest with a phone. The show is written into the script in advance and starts from the sound desk at the right moment
- Can it replace fireworks?
- Yes, a frequent request: fireworks are banned in public areas, while cold fountains and smoke only work on stage. A light salvo from the guests’ phones closes the night, works indoors and needs no permits
- Does it fit a conference or an award ceremony?
- Yes. The format works as an energizer between sessions or as the ceremony finale: the room answers questions from the stage with light and gathers into one picture at the end. No app needed, just a QR code on screen
- Is this an immersive show?
- Yes, in the most literal sense: viewers are not placed inside someone else’s action, they create it themselves with their phones. See the comparison with immersive plays and theatrical dinners in the immersive show formats overview
