Fagerhult has unveiled a Twin Dual Driver which powers two luminaires and cuts total environmental impact by 49 per cent compared to two separate drivers.
The luminaires can be up to 4.8 metres apart.
Fagerhult says the context to this development is the fact that drivers haven’t evolved at the same pace as luminaires.
‘Over the years, we have seen one Fagerhult luminaire after another become meticulously refined, more efficient, lighter, smarter, and made with better materials. But the electronics didn’t evolve at the same pace,’ Fagerhult product and application manager Lars Eriksson told the Circular Lighting Report. ‘We asked ourselves: could we make a change here?’
The Twin Dual Driver – developed in association with Helvar – boasts streamlined electronics, recycled post-consumer plastic in housing – and a 49 per cent overall reduction of CO2e (when comparing EPDs, GWP Fossil A1–A3: Twin Dual Driver and two drivers with equivalent functionality).
Twin Dual Driver enables quicker installations – with fewer luminaires – in large-scale applications and spacious facilities. It comes with cable lengths up to 3 meters, and is equipped with a quick connection system that allows tilting of the primary side connection and easier installation in low or narrow ceiling spaces.
The Twin Dual Driver is compatible with the light control system Organic Response. This enables synchronised control of the two luminaires, full system integration, and enhanced functionality. As two luminaires are controlled via the same DALI address, each DALI system can double its size compared to the number when using single drivers. The Twin Dual Driver is certified as DALI-2 with memory banks 251-253.
DALI versions use the standard five-way ‘blue’ solution, while three-way is offered for Organic Response-enabled luminaires. Both systems can be used for onward connection, together with an appropriate T-splitter.
The driver can also be connected as a permanent installation including the possibility of loop-in, loop-out connection.
