Used for centuries as the tool to both teach and communicate mathematics, the abacus was found in one form or another across the ancient world. At Terzani, we saw the beauty in the abacus? mathematical purity and clean, functional design. In the hands of Terzani's craftsmen, we have turned this inspiration into a new collection of modular pendant lamps whose flexibility allows for complex and beautiful configurations. Each module, or strand, of Abacus contains a custom set of round, hand-blown opal glass which emit a soft and uniform light. And, as the original abacus was used to calculate everything from simple addition to complex formulas, Terzani has retained the same scalability. Due to its customization, our Abacus light is just as suitable in a home as a commercial space, with an array of almost infinite configurations.


All single elements and clusters can DIM with both 0-10V PWM (included as standard) or DALI (optional)

This product is designed for flexible use as either a single element or as a cluster. Ceiling roses/wall brackets must be chosen and added for every pendant. If you decide to use your own canopy, please be aware that the standard manufacturer's guarantee will no longer be valid.


This modular product encourages the creation of bespoke ceiling compositions. If you would like to create your own ceiling clustering/pattern, you have 2 options:

1] Select the "pendant only" option above, in the number of Spheres required, and add the desired quantity to the quote; you can then calculate the number of required transformers by using the table in the ABACUS TRANSFORMERS page.

It goes without saying that if you have any questions, you can pick up the phone and give us a ring!

2] Create a bespoke shape and size ceiling plate. This option is usually more time consuming, has longer lead times and higher costs. Please contact the office to discuss further:
