A tree built in stacked modules

A 12 m tree cannot travel as one object, so the trunk, branch tiers and topper are engineered as separate steel modules that bolt together on site. Each ring of branches locks to the tier below it, which means the piece arrives as a handful of flat-packed crates rather than a single oversized load that a standard truck cannot carry. The advantage for a mall or city plaza is that the same tree can be re-erected year after year, and individual tiers can be left out if a ceiling or canopy limits the height at a particular venue. The module joints are concealed once the silk is dressed, so the assembled tree shows no seam lines under the light.

Because the tree arrives as modules rather than one assembled object, most of what a venue has to arrange happens before delivery rather than on installation day. The ground has to take the base anchoring specified in the installation drawings, the electrical supply needs to match the published 110/220V AC configuration and the 50 to 300W power band by scale, and a boom or cherry picker needs access at dress-up time to reach the topper and the upper tiers. A dry store for the flat-packed tiers belongs to the same plan, because the modules only come back in good order if they are kept that way between seasons.

More than three thousand points of light

The surface carries over 3,000 individually addressable LED points set into the silk rather than clipped to the outside, so the light reads as coming from within the foliage. That density is what lets the tree hold a steady warm glow from across a concourse and then shift to a chase or a breathing effect as visitors come closer. Because the points are distributed on the internal steel frame, the silk can be removed and re-dyed or re-covered without disturbing the lighting layout, which is the part that wears first outdoors. The points are sealed for the -30 C to +50 C operating range.

The star topper runs on its own programme

The topper is a separate lighting zone, programmed independently from the body. It can hold a slow rotation of colour while the tree beneath stays a single warm white, or it can act as the climax of a timed sequence that sweeps from base to tip. For a sponsored installation the star can be tuned to a brand colour and left steady while the rest of the tree runs animation, which keeps the logo readable from a distance. The controller stores several programmes so the venue can change the mood without our team returning to site.

Standing through a full winter

The galvanised, anti-rust frame and sealed low-voltage lighting are built for the -30 C to +50 C operating range, and the silk is fire-retardant and painted with all-weather coating. Snow load is handled by the taper of the modules and the fixing detail at the base; the installation drawings specify the ground anchoring for the local wind and snow rating. Between seasons the modules store flat, which is what makes a 12 m tree practical for a venue that only needs it for six weeks of the year and must reclaim the floor afterwards.
