Commencing 1 November 2009, certain general purpose incandescent lamps (tungsten filament and tungsten halogen) will be required to comply with Minimum Energy Performance Standards (MEPS) that are set out in AS 4934.2 in Australia. Test procedures for Incandescent Lamps are set out in AS/NZS 4934.1.
Note: MEPS Requirements for Incandescent Lamps do not apply in New Zealand.
From 1 February 2009 there has been an import restriction for general lighting service (GLS) incandescent lamps implemented through Commonwealth Regulation.
Further information is available on the Australian Customs and Border Protection Service website
The intended timeline for certain lamps being subject to MEPS is as follows:
|Lamp Types||Sales Restriction From|
||1 November 2009|
||1 October 2010|
||1 January 2011|
||1 October 2012|
Date to be reviewed and determined dependent on availability of efficient replacement products
||To be determined dependent on availability of efficient replacement products|
The definitions of Lamp Types in the above table can be found in the summary of Part 2 of the Australian Standard. These include tungsten filament and tungsten halogen lamps with varying voltages, wattages, shapes and lamp caps, used for general purpose lighting. MEPs will also be applied to Compact Fluorescent Lamps (CFLs).
MEPS improves end-use energy efficiency by eliminating lower efficiency lamps from the market.
MEPS for incandescent lamps are set out as minimum Efficacy (in lumens per Watt). The required minimum initial lamp efficacy (in lm/W) is given by the formula:
Initial efficacy: Average value shall be ≥ (2.8 ln (L) − 4.0)
Where In (L) is the natural logarithm of the measured initial luminous flux (in lumens)
The curve resulting from this formula is depicted in the figure below.
Linear Fluorescent Lamp GraphUntil 30 September 2013, when tested in accordance with AS/NZS 4934.1, mains voltage halogen non-reflector lamps may comply with an alternative initial efficacy requirement, as follows:
Initial efficacy: Average test value shall be ≥ 0.95 x (2.8 ln (L) − 4.0)
Refer to Regulatory Ruling #43C for more information on mains voltage halogen non-reflector lamps.
There are also requirements for Lumen Maintenance (minimum of 80% measured at 75% of rated lamp life) and Minimum Lamp Life (median lamp life of at least 2000 hours). The methods for measurement of efficacy, lumen maintenance and lamp life are set out in AS/NZS 4934.1.
