The Pierlite T5 Streetlight

• Integral Energy NSW Concept
• Replacement for the 80w MV and 2 x 18/20w that
  will meet AS/NZS1158 and AS/NZS3771 standards.
• Longer lamp life to extend maintenance period.
• Provides better visual guidance and orientation
  along the road.
• Energy efficient with low running costs.
• IP 65 to allow better maintenance factors.
• High quality white light.
• Looks good.

New Luminaire components

• Selected
• T5 14w standard and 24w HO Lamps.
• ECG gear.
• To achieve
• High efficiency with AS compliant optics.
• Reliable luminaire that will meet standards.

T5 Fluorescent lamp - background

• Released in 95 - not new and unproven.
• Developed by worlds leading lamp companies
  Osram, Philips and GE.
• Almost all new commercial projects now use it.
• Different parameters to be considered in design .

T5 Key Performance Factors

• Smaller diam 16mm better efficiency 5
• High lumen output-up to 90 lm/w, double MV.
• Long life - expect over 20K hours - many examples
  
• Osram T5 data on 3 hr cycle shows 10 lumen
  depreciation at approx 18k hours.
• Low mercury to dispose at end of life - 3mg vs
  60-100mg for MV legislation pending already
• Lamps enclosed so low temperature operation
  possible and drop in output not significant.
• Excellent colour rendering and choice of colours.

6
ECG Ballast Background

• Over 20 years and 500,000 pieces sold in
  Australia p/a.
• Will become main ballast type in next few years
• Not just fluorescent, also HID.
• Reliable,cheap,cost effective.
• Choice of suppliers from leading companies.
• To IEC standards on surge and over voltage
  protection. Fittings comply with AS3771 high
  voltage surge test.
• Used in exteriors,streetlighting, industrial,
  tunnels already in Europe USA, Latin America and
  Australia
• Additional protection from surges available at
  low cost if required for specific areas.

T5 ECG Key Performance factors

• Total circuit watts of 2 x 14w ECG only 31w, 2 x
  24w only 52w.
• Replacing 2 x 18/20w immediate 30 power
  reduction
• Replacing 80w MV immediate 65 power reduction
• ECG extends lamp life.
• ECG will provide constant light output with
  voltage fluctuation .Our supply varies 230-260v,
  standard gear will vary light output
  substantially.
• Guaranteed for 5 years, typical life in excess of
  100,000 hrs long cycle.

Key features and benefits

• IP65 for better sealing, longer maintenance
  cycles
• High impact acrylic lens, smooth exterior easier
  to clean
• Silicon gasket attached to lens
• Rugged Die cast aluminium body
• 4 Stainless clips allow diffuser to hinge for
  maintenance
• Reflector assembly easily removed
• Lamp compartment sealed at factory and not opened
  during installation to keep lamp area clean
• Separate wiring compartment cover push fits on
  after installation
• D2 cell base can be supplied

11
Technical compliance

• IP65 test certificate NATA
• AS3771 key areas including Impulse test
• AS3771 and 60598 thermal endurance and safety
• C tick mark for EMC compliance
• Osram 5 year ballast guarantee
• AS3771 Wind test assessment
• Mounting to AS3771 , 34mm OD spigot
• 3 pole terminal block, optional FTB
• Cable clamp to AS3771

Performance

• High performance reflector and lens.
• 84 LOR, 4 UWLR
• To maximise output and spacing.
• At most P4 and P5 road width and spacing criteria
  Greenstreet 2 x14w matches 80w MV performance
• A GS214 can therefore replace MV80 with huge
  energy savings
• When replacing TF20,power is reduced by 1/3 and
  maintenance improved from 18 months to 4-5 years.
  
• Design will comply with AS category P5 in most
  cases

15
Additional performance factors

• With 24w lamps the fittings operate warmer and
  will suit very cold conditions, to sub zero
• With 14w lamps fitting will start to - 20 C but
  light output at 0 deg or lower can fall below 80
  of max.
• This is not a problem for most areas of Australia

Using 10,000 x 14w T5 streetlights instead of 80W
MV will save

• 2,480 MWh of electricity being generated per
  annum.
• 2,500 tonnes of CO2 into the atmosphere.
• Big savings for CCP councils.

Summary

• T5 lamp is much more efficient than mercury and
  T8 fluorescent.
• In most P type applications the T5 can replace a
  20w fluorescent or 80w mercury streetlight.
• The 2 x 14w uses only 33 of the power of an 80w
  mercury light.
• Maintenance is reduced due to better sealing and
  longer lamp life.
• Greatly reduced mercury content
