Australias Road Lighting Standards into the
energy efficiency age

Committee Lighting for roads and public spaces

Into the energy efficiency age

• What Road lighting ?
• There are about 2 million luminaires in service
  in Australia
• 30 are on main roads - Cat V and 70 on local
  roads - Cat P
• Cat V - 250/400W lamps, Cat P - 40/80W lamps ?
  energy equal
• Projected increase 1.5-2 per annum - 45 over
  past 14 years
• Costs - 10 a resident, 1m LG budget, 1-2 LG
  outlays

Into the energy efficiency age

• How is energy efficiency being mandated?
• Originally part of the AGO Greenlight program
• To be implemented by compliance requirements in
  Standards
• - AS/NZS 1158 Lighting for roads
  and public spaces
• Traffic route lighting Category V
• - MEPs in W/m for HPS and MV for Cat V1 to
  V5
• - Maximum ballast loss
• -Encourage service providers to
  replace low efficacy HPM (30 of total)
• Pedestrian lighting Category P
• - Encourage good practice
• - Trials of energy efficient luminaires

4
Into the energy efficiency age

• Recent amendment of 1158.1.1 Category V
• LAMP REQUIREMENTS
• Normally lamps used in Category V lighting
  schemes shall be HPS lamps
• Where either the client or the lighting designer
  has documented that the colour
  rendering characteristics or colour appearance
  characteristics of HPS lamps are inadequate for
  the application, in which
  case MH lamps shall be used.
• Applications where MH is deemed to be necessary
  include the following
• - Cat V lighting in town and city
  centres.
• - Cat V lighting in or close to
  retail, commercial or entertainment precincts.
• The use of HPM lamps in Category V lighting
  schemes is not permitted.
• Ballast losses not greater than in 1158.6
  Luminaires

5
Into the energy efficiency age

• Energy efficiency in Cat P
• Cat P - large potential gains with newest CF
  and T5 lamps plus electronic ballasts
• Energy usage by lamp type (including
  control gear)
• Lamp CFL 42W T5 2x14W HPM 80W
  TF 2x20W
• Energy 47W 30W
  89W 50W

6
Into the energy efficiency age

• But are they reliable?
• Equivalent 1st year failure rates from trial
  of
• 1175 T5 (20 months) and 250 CFL luminaires (17
  months)
• Luminaire Lamp failures
  ECG failures
• 2x14W T5 trial 1.6
  0.5
• 42W CFL trial 1.7
  0.6
• 80W HPM historical 3.2
  NA
• Results indicate no technical bar to use

7
Into the energy efficiency age

• What about lighting performance?
• Indicative spacings for the different luminaires
  
• H 7.5m Road reserve 20m
• Luminaire Category P3
  Category P4 Category P5
• 2 x 14W T5 26.1m
  65.7m 81.9m
• 42W CFL 36.7m
  70.6m 84.1m
• 2 x 24W T5 41.8m
  74.5m 89.1m
• 80W HPM 43.7m
  71.5m 87.2m
• 2 x 20W T8 -
  17.9m 48.9m

8
Into the energy efficiency age

• Recent amendment of 1158.3.1 Cat P
• Luminaire Type 4
• The intensity at any angle of azimuth shall be
  not more than
• (i) 720 cd in total or 180 cd/1000 lamp
  lumens, whichever is the greater,
  at a vertical angle of 80
• (ii) 300 cd in total or 80 cd/1000 lamp
  lumens, whichever is the
  greater, at a vertical angle of 90.
• The changes are necessary because the original
  criteria inadvertently technically disadvantaged
  luminaires with energy efficient lamps, i.e. T5
  and CFL. The change to absolute cd units is based
  on the in-service 80 W HPM.
• The new luminaires have cd values much below
  that value. The original criteria are retained
  for the higher wattage luminaires.
• T5 and CFL to be included in 1158.6 Luminaires
• Ballast losses set by regulation

Into the energy efficiency age

• NSW - with the encouraging results of the
  trials, Energy Australia has offered its
  customers the choice of the luminaires using CFL
  and T5 lamps. Over the next six years a
  program to replace 60 000 obsolescent
  2x20W TF luminaires will be implemented
• What is happening in other States?
• Queensland - 3year trial of 300 luminaires,
• fully instrumented, continuously monitored
• Victoria - 300k 80w HPM luminaires recent
• cost determination by regulator Councils can
• proceed at own pace 32W CFL favoured
• Tasmania T5 favoured
• South Australia?
• Western Australia?
• Overall we have not proceeded far into the energy
  efficiency age in public lighting

10
Into the energy efficiency age

• Are there OTHER potential ENERGY EFFICIENCY
  MEASURES?
• Zero upward light cut-off lighting requires
  more points - UWL
  Cat V 1 and Cat P 5
• Lower light level 1158 light level low (Cat V)
  to very
  low (Cat P) compared to CE and EU
• Dimming or switching out for reduced traffic/late
  hours Cat V is
  good accident counter measure
• LED lighting still developing and untried in
  field
• Solar power isolated rural sites only
• Cat V lamp ballasts
• In Australia efficient lamps give best viable
  option

• In perspective Aus road lighting
  
  
  
• is in good shape compared to
  
• that in some countries!
