Brisbane City Council and Energex are currently trialling ten different types of LED lights in 17 residential streets across Brisbane.  Some limited information on the nature of the trial is available from Brisbane City Council, here.

A total of 100 LED lights have been installed for the trial.  Brisbane City Council has made public very little information about these lights and how their performance is being evaluated.

We have inspected all 17 trial streets by day and night and compiled our own evaluation of the performance and suitability of each LED light for Brisbane-wide deployment following completion of the trial.  A brief overview of our findings is presented in the following table:

We consider the design and operation of the trial to be very deficient from multiple perspectives.  In our assessment none of the trial LED lights are suitable for Brisbane-wide roll-out.

A short PDF document outlining our findings for each trial street is available by clicking any of the trial streets listed below:

A very detailed submission to Brisbane City Council and Energex, addressing technical aspects of street lighting and the performance of the trial lights, can be obtained here.

 

What We Ask of Brisbane City Council and Energex

We have serious concerns about the current LED street light trial.  We consider none of the light being trialled are suitable for roll-out across Brisbane residential streets. 

We ask Brisbane City Council and Energex to recognise Brisbane residents will need to live with their LED luminaire selection outside their homes for the next 20 years or more. 

We ask Brisbane City Council and Energex please keep protection of resident’s quality of life at the forefront of your LED trial and decision-making.

We ask Brisbane City Council and Energex senior management and elected representatives to take a much greater interest in the LED trial, its design, its operation and its outcomes. 

We ask that a wider range of LED luminaires be trialled to find those that best place the light that is needed where it is needed and minimise negative impacts on residents.  The main negative impacts observed in the trial are – over-illumination beyond the task minimum requirement; excessive glare; excessive colour temperature; excessive light trespass; very poor luminaire installation.

Brisbane City Council and Energex engineers have a difficult task and must consider a wide range of competing factors and criteria when selecting which LED luminaires will be deployed across Brisbane and the wider SEQ region. 

However, to best address resident’s quality of life aspects of street lighting we ask that the trial and eventually select LED luminaires incorporate the following aspects of design:

  • An up-tilt angle adjustment mechanism as an incorporated component of the luminaire.
  • A 7 pin NEMA receptacle.
  • Colour temperature no higher than 3000K.
  • Glare control through shielding down to at least 800
  • Watts/Lumens rating to achieve the minimum task area lighting required by the Australian Standard for the P classification street where the luminaire will be deployed.
  • Forward and rear light pattern controlled to keep the primary beam within the boundary-to-boundary public road reserve and not create light trespass onto homes regardless of road width or building set-back from the boundary line

Since Brisbane’s Category P roads are quite diverse in terms of width, property set-backs, pole spacing and topography, we expect a range of luminaires will need to be specified to allow the best option to be installed for each circumstance. A one-size-fits-all approach is not possible.

But above all, we ask Brisbane City Council and Energex to please keep protection of resident’s quality of life at the forefront of the LED trial and your decision-making for subsequent Brisbane-wide roll-out.
