200 luminaires are reused at City livery company

Haberdasher's Hall where lights have been reused

Almost 200 luminaires have been reused in a lighting upgrade at Haberdasher’s Hall in London.

The lights were upgraded by the luminaire remanufacturing firm Silent Design using control gear from Tridonic.

The team at Tridonic UK were asked to provide wireless lighting solutions for the refurbishment of the building in Smithfield, which is used by the Company for various events.

It had to be easy-to-use and retrofit, whilst also upgrading the existing lighting that had started to experience failures. The lighting also had to enhance the natural wood fixtures and finishings that provide a sense of modern opulence.

Wireless controls were a necessity to ensure the wiring infrastructure in the call would remain intact.

Retrofitting involves adapting existing luminaires for new components. This meant that extensive engineering, measuring, and prototype testing was required to achieve the required result. The Tridonic’s LEDs worked seamlessly with the LEDiL holders and reflectors. Opting for remanufacturing over purchasing new fittings significantly cut the building’s carbon footprint and the amount of waste going to landfill.

All light sources were Tridonic SLE G7 LEDs, with a colour temperature of 3000K and a high colour rendering of RA>90, a highly customisable solution that helped to accentuate the true colours of the natural wood finishes in the hall.

Tridonic supplied 189 basicDIM Wireless drivers, facilitating control of the luminaires to dim from 1-100 per cent. By using bDW drivers, the solution gave the client flexible control of each luminaire, for easy scene setting; bespoke scenes and groups, allowing the end user to make adjustments to the lit environment to achieve their desired ambiance.

Thanks to the enhancements made, the total energy savings per year will be 43087.51kwh, with a carbon saving per year of 23267.26kg. Over five years, the cost saving (based on 0.15p per kwh) will be £32,316.

Using remanufacturing techniques during the retrofit the project has saved 178.1kg of waste from going to landfill.

The project has now been nominated for a Build Back Better Award in the lighting categor

The designers on the project were James Huntington and Dan Bamforth.
