BigHit Music has officially unveiled the BTS OFFICIAL LIGHT STICK VER. 4, marking the first major update since the Special Edition release nearly six years ago. This latest ARMY Bomb introduces a refined look along with noticeable upgrades in performance and interactivity. Whether you’re preparing for their upcoming world tour or simply adding to your BTS collection, here’s a full breakdown of what makes VER. 4 different — and whether it’s worth the upgrade.
This release goes far beyond a simple redesign. VER. 4 reimagines how the light stick functions during concerts and in everyday use.
Multi-Zone LED System: The globe now contains multiple internal lighting sections instead of a single uniform light source. This allows the light stick to display layered colors, flowing effects, and dynamic transitions that feel more immersive during live shows. Because of this upgraded system, older ARMY Bomb versions will no longer be supported for certain concert lighting sequences starting from Festa 2026.
Improved Wireless Synchronization: ARMY Bomb VER. 4 features an upgraded control system that enables smoother color changes and a wider range of tones. This allows the light stick to respond more precisely to stage cues, making large-scale crowd effects feel more seamless.
Pre-Concert Pairing Check: A new pairing feature lets your ARMY Bomb sync with nearby light sticks before the show begins. If your light stick lights up in harmony with others around you, you’ll know you’re properly connected — no more second-guessing once the concert starts.
Brand-New Companion App: The updated app adds several new functions, including a venue map to locate pairing stations, a concert log that records the shows you’ve attended, and a “Self Mode” that lets you use the light stick at home for ambient lighting.
Shake-to-Change Colors: In Self Mode, users can now switch colors by simply shaking the light stick, adding a playful and interactive touch when using it outside of concerts.
For the first time, the ARMY Bomb is part of a customizable system with optional accessories sold separately.
The Cradle accessory allows you to display your ARMY Bomb as a decorative lamp at home. It connects via USB-C to power Self Mode, though the light stick itself still relies on batteries for portable use.
Fans can also purchase interchangeable decorative pieces featuring BTS and ARMY branding, allowing for more personalization than ever before.
Despite the tech upgrades, VER. 4 does not include a built-in rechargeable battery. According to official product details, it continues to use three AAA batteries, similar to previous versions.
ARMY Bomb VER. 4 feels like a true evolution rather than a minor refresh. With enhanced lighting effects, smarter concert syncing, and new customization options, it’s clearly designed with BTS’s next chapter in mind. Whether you’re planning to attend the ARIRANG World Tour or simply want the most up-to-date version for your collection, this release sets a new standard for official K-pop light sticks.
