ProX 20" Mirror Disco Ball with 3/8" Glass Tiles | Bright Silver Reflective DJ Sphere with Hanging Ring

Introducing the ProX MB-20 20" Mirror Disco Ball, a full-size professional reflective sphere built for nightclubs, ballrooms, large bars, event production rigs, and any venue where the room demands a statement. At 20 inches, the ProX MB-20 crosses the threshold from accent piece to centerpiece. The beam throws grow longer, the reflection field covers more of the ceiling and walls, and the overall effect becomes the kind of immersive dance floor signature that defines a serious lighting installation. If you are building a permanent venue install or loading a production rig where the visual impact has to be real, this is where it starts.

Core Construction The MB-20 is built around a high-density Polystyrene foam (EPS) core, the gold standard material for professional mirror ball manufacturing. The closed-cell EPS structure delivers the rare combination of low weight, high rigidity, and true long-term dimensional stability that a ball of this size demands. It resists moisture absorption, holds its shape under continuous stage lighting heat, and maintains an accurate spherical profile through years of nightly use and repeated transport. A stable, perfectly round core is what keeps rotation smooth and light distribution even across the entire surface at every show.

Glass Mirror Tiles The full exterior of the MB-20 is finished with precision-cut, high-grade glass mirror tiles measuring 3/8" (10mm). Each tile is produced to consistent thickness with clean square edges for tight, uniform edge-to-edge placement across the sphere. Every tile carries a premium silvered backing delivering maximum reflectivity, true color rendering, and crisp beam definition when hit by a focused light source. The mirror coating is sealed against tarnishing and discoloration, maintaining its bright silver finish through years of continuous professional event and venue use.

Tile Adhesion and Density Every tile is individually bonded using a professional-grade high-strength adhesive engineered to hold firmly through continuous motor rotation, vibration, transport, and the demands of touring and nightly venue environments. ProX mirror balls use an increased tile count compared to traditional mirror balls of the same size, producing a denser pattern of reflected beams and brighter, more saturated light coverage across walls and ceilings with every revolution.

Mounting Hardware A reinforced steel center rod runs the full vertical axis of the ball from top to bottom, providing a solid internal backbone for hanging and rotation. At the mounting point, a heavy-duty removable O-ring and M10 nut create a secure, balanced anchor for hanging hardware and motor attachment, built to support the ball reliably through long runs of continuous rotation.

Motor Compatibility The MB-20 is designed to pair with the ProX X-MBM-2 (1 RPM) mirror ball motor, available separately through ProX Direct. It also works as a universal fit with any standard 1 RPM rotator on the market.

Compliance and Weight The MB-20 is CE and RoHS compliant. Net weight is 3.1 kg (6.85 lbs).
