QTX 100cm Polyethylene Disco Ball - 7mm Mirror Tiles

The QTX 100cm polyethylene disco ball is a 1-metre diameter sphere covered in 7mm polished mirror tiles, built around a lightweight polyethylene core with dual hanging points. When lit by a pinspot or moving head, the tiles scatter thousands of moving light points across a room, creating the classic disco ball effect at a scale that fills large venues.

Designed for theatres, nightclubs, wedding venues, concert halls and stage productions, the 100cm diameter makes this a centrepiece installation rather than a secondary effect. The dual hanging points distribute the 42kg weight across two ceiling fixings, reducing the load on any single point and adding redundancy for professional installations where safety is non-negotiable. The polyethylene core keeps the weight substantially lower than a comparable solid-core ball, simplifying rigging and reducing the structural requirements on the mounting point.

The 7mm mirror tiles are individually glued onto the polyethylene sphere in overlapping rows, giving a higher tile density and more intense light scatter than cheaper 10mm-tile models. Each tile is made from glass mirror with a protective backing, so the reflections are bright and consistent under spot lighting. The dual hanging loops are metal and bolt through the core, not glued to the surface.

At 1 metre diameter, this ball suits rooms with ceiling heights of 3.5m or above to allow clearance for rotation if motorised. For static installation in lower-ceiling venues, the ball can be hung at a height that keeps it visible but out of the way of stage performers. The polyethylene construction means it can be handled and installed without requiring specialist lifting equipment, though a two-person team is still recommended due to the 42kg weight.

What ceiling height is needed for a 100cm disco ball?

For static installation, ceiling heights of 2.8m or above work, with the ball hung at a height that keeps it visible but clear of performers. If you're planning to rotate the ball with a motor, ceiling heights of 3.5m or above give better clearance and allow the light scatter to reach the floor without obstruction.

Can this ball be rotated with a standard mirror ball motor?

Yes, but the motor must be rated for at least 42kg load. Most consumer-grade mirror ball motors are rated for 10-20kg maximum and will not safely support a 100cm ball. QTX and other professional suppliers offer heavy-duty motors rated for 50kg or above specifically for large-diameter balls.

How is it hung safely?

The dual hanging points allow two separate ceiling fixings, spreading the 42kg load and providing redundancy. Each hanging point should be fixed to a structural beam or joist capable of supporting at least 60kg static load (to allow for dynamic movement if motorised). Do not hang from plasterboard ceiling fixings or surface-mounted track.

What's the difference between 7mm and 10mm mirror tiles?

The 7mm tiles are smaller and more numerous, so they create a denser coverage and more intense light scatter. Cheaper disco balls use 10mm tiles, which cover the surface faster during manufacture but produce fewer individual reflections. For a professional installation, 7mm tiles give a noticeably brighter and more complex effect.
