Auckland Council Orewa Road Lighting Technology Trial

Modus Lighting supplies Auckland Council the LED lighting and controls that deliver major energy and environmental savings.

There has been much activity in recent times with various New Zealand local councils exploring new road lighting efficiency concepts to identify energy, environmental and financial savings opportunities.

The Electricity Commission “RightLight” Efficient Road Lighting Programme that rolled out last year promoted processes and guidelines to encourage the undertaking of council road lighting technology trials and assessments.

Damon Birchfield, Energy Efficiency and Environment Officer at the (then) Rodney District Council was a participant in the EC training workshops and wished to progress the opportunity within the Rodney District with a well researched and rigorous road lighting efficiency study.

This has resulted in the Auckland Council Road Lighting Technology trial at West Hoe Road, just off State Highway 17 Orewa, north of Auckland. This trial deploys best practice LED road lighting fittings with advanced electronic control and dimming systems.

Philips SpeedStar Luminaire as Installed in Orewa Trial

Modus Lighting Ltd was the equipment supplier, IT designer and systems integrator for the project.

BEFORE - Traditional HPS Lighting at 100% light level

AFTER - MODUS LED Lighting at 100% light level

As well as LED appraisal, a significant part of this trial was to evaluate the practicalities of adaptive lighting for NZ roading conditions, as a means of achieving operational savings. Adaptive lighting is the selective adjustment (up or down) of lighting levels during different stages of the nightly period in accordance with the exact needs of the prevailing traffic and pedestrian activity levels.

The new lighting equipment on trial delivers full light output at high activity periods, is dimmed by 50% at shoulder periods and is dimmed by 75% at low activity periods.

AFTER - MODUS LED Lighting dimmed by 50% to 50% light level.

AFTER - MODUS LED Lighting dimmed by 75% to 25% light level

The trial employs Philips SpeedStar LED light fittings combined with Philips advanced electronic light level dimming and control to adjust the light output to deliver the exact amount of light required for the conditions, minimising waste light and waste energy.

The results of the whole-of-life assessment over a 30 year period are -

a) Energy saving (kWh) vs currently installed orange light (HPS) technology = 54% saving

b) Energy saving (kWh) vs traditional white light (MH) technology = 73% saving

All of the improvements are attainable at a lower whole-of-life financial cost than that of traditional High Pressure Sodium or Metal Halide technologies of an equivalent quality level.

Further details of the trial are available from Modus lighting Ltd General Manager, Chris Byrne at chrisbyrne@moduslighting.co.nz

Modus Lighting is now ready and able to supply NZ councils with energy and money saving technologies that far outperform outdated traditional options.

Hybrid lamp - CFL/Halogen.

GE introduces 'hybrid' bulb with both halogen and CFL elements. Itt's like two bulbs in one, the halogen unit powering on almost instantaneously then fading off once the CFL element gets itself all riled up. It is brightness than current covered CFLs and great design!

Art in the Dark 2010

Art in the Dark, an interactive community event, is set to light up Ponsonby's Western Park on the 15th and 16th of October 2010, from 7pm until late.

Modus are thrilled to be working alongside the Dry Dairy collective on their installation for Art in the Dark, especially after the amazing pavilion that they created at Splore this year lit with Philips Color Kinetics.  Be sure to mark this event in your calendar and get along to Western Park to check out not only the Dry Dairy installation but the whole event for yourself! 

New agency - Brick In The Wall

Modus has had the recent pleasure of becoming the new agent for another unique brand out of Europe.

Specifically from Belgium, Brick in the wall manufacture a range of light fittings which are totally borderless. Designed for that minimalist look, all of these fittings can be recessed into either concrete or normal gib walls then painted the same colour as the rest of the wall.

Bringing Colour to Dunedin!

Last week, our South Island Team, from Mark Herring Lighting put on a great colour lighting demonstration  at the Historic Dunedin Railway Station. We can't say that this treatment would be 'advantageous' for this amazing historic building, but as a canvas for providing education and illustration of what can be achieved with coloured light- it was fantastic! This turned out to be great night- thanks to all that attended! (and Trevor even got his picture in the paper!)

Light & Building Fair - Frankfurt :Next Generation Lighting Gets Real

As they have been for the last 20+ years, Modus people were busy exploring this year’s Light and Building Fair in Frankfurt in April.  Every two years this massive event showcases the very best lighting design and R&D efforts from the international community.
