The length of the garland is 40-100m the step is 40-50cm the base is E27.

The garland was created using Corona Scatter the composition is edited
through a spline (wire). The number of lamps automatically changes depending on
the length of the wire with the same pitch.
The Spacing value sets the pitch of your choice.

It is important that sharp corners in the spline should be of two vertices otherwise the wire cross section is twisted and some of the lamps will look up or to the sides.
In case of incorrect intersection of the wire of all cartridges correct through the main (yellow) vertex the initial direction of the spline is horizontal.
The scene should be in mm.
