Emerging lighting technologies
This page outlines how to have emerging lighting technologies accepted for use under the Energy Savings Scheme
Under the Energy Savings Scheme, the use of emerging lighting technologies in energy savings activities must achieve a reduction in energy consumption without reducing the level of service or output provided by the original lighting equipment.
What are emerging lighting technologies?
Emerging lighting technologies (‘ELTs’) are those technologies for which one or more of the following apply:
- they are not fully developed, or have not been widely accepted by the lighting industry
- no recognised mandatory performance, design, or efficiency standards apply
- there is a high degree of variation between products
- they are subject to misleading claims.
ELTs include LED lighting equipment, induction lamps, T5 linear fluorescent adaptor (T5 adaptors) and voltage reduction units (VRU).
Applying the Commercial Lighting Energy Savings Formula to establish energy savings
ELTs are not assigned a default Lamp Circuit Power (LCP) for use in the Commercial Lighting Energy Savings Formula. Instead, the ESS Rule (Table 9 of Schedule A) requires that the:
“Proponent shall apply to the Scheme Administrator in advance for LCP value, and supply specification sheets or laboratory test reports. Control gear losses shall be included in the LCP.”
The ESS Rule (Table 10 of Schedule 1) outlines specific treatment of T5 Adaptors and VRUs, as they are not assigned Default Operating Factors.
Acceptance of emerging lighting technologies - ELT Portal
Existing Accredited Certificate Providers can apply to have emerging technologies accepted for use in specific projects in the Energy Savings Scheme. In order to submit an application requesting acceptance for an emerging lighting technology, you must submit an application via the Emerging Lighting Technology (ELT) Portal.
The ELT Portal is a web interface which allows ACPs accredited under the Commercial Lighting Energy Savings Formula to submit applications for acceptance of ELT and to track progress of ELT applications.
Where the Scheme Administrator is satisfied with the information provided, notice will be provided that the equipment is accepted for use in the energy savings project. The approved lighting technology values should be entered into the Commercial Lighting Tool (version 3.2, 5 November 2012) to calculate your energy savings. As of 2 August 2012, the Scheme Administrator will not be issuing modified versions of the Commercial Lighting Tool each time an emerging lighting technology is accepted for use in the Energy Savings Scheme.
Note: the Scheme Administrator does NOT approve products.
As such the Scheme Administrator does not publish a list of products previously accepted for use by Accredited Certificate Providers and will not consider applications from manufacturers or other agents.
Using emerging lighting technologies in the Energy Savings Scheme
The following areas be addressed before emerging technologies can be accepted for use in the Energy Savings Scheme:
- electromagnetic compatibility (EMC) and electrical safety
- lamp circuit power
- asset lifetime.
1. Electrical safety and electromagnetic compatibility requirements
For full details of the electrical safety and electromagnetic compatibility (EMC) requirements applicable to particular lighting equipment, please refer to the table below:
Required documentation for emerging lighting technologies61.86KB PDF FileDetailed documentation required for emerging lighting technologies including specifications, lamp circuit power, output voltage, electrical safety and electro magnetic compatibility
These requirements apply to lighting equipment connected to mains voltages (240V) that is considered as emerging technology to ensure that they meet:
- the electromagnetic compatibility (EMC) requirements under the Radio Communications Act 1992 as administrated by the Australian Communication and Media Authority, and
- the electrical safety requirements under the Electrical (Consumer Safety) Act 2004 as regulated by Fair Trading (NSW).
The electrical safety requirements that apply to your lighting equipment depend on whether the equipment is a declared or non-declared article.
The Electrical (Consumer Safety) Act 2004 classifies particular types of equipment as ‘declared articles’ (which includes lamp ballasts and T5 adaptors).
To sell a declared article in NSW, you must obtain an Australian Certificate of Approval from either Fair Trading (NSW), or another certification body recognised by Fair Trading (NSW) i.e. other state safety regulators, or recognised independent certifiers.
You must provide us with a copy of the Australian Certificate of Approval for your declared article for it to be accepted for use in the Scheme.
Non-Declared Articles are those types of equipment not listed as declared articles under the Electrical (Consumer Safety) Act 2004 (which includes VRUs and lamps with integrated ballasts, such as LED tubes and induction lamps).
You must provide us with a copy of the electrical safety certificate for your non-declared article, issued by either Fair Trading (NSW) or another state safety regulator, for it to be accepted for use in the Scheme.
This requirement applies to all lighting equipment connected to mains voltages (240V), especially LED tubes, as numerous safety warnings for LED tubes have been issued by various safety bodies. This requirement does not apply to extra low voltage (ELV) lamps that are connected to non-integrated (i.e. physically separate) control gear.
2. Lamp circuit power
Evidence must be provided to demonstrate the Lamp Circuit Power (LCP) for each specific lamp and associated control gear combination you propose to use.
The information you submit for your product must clearly show the LCP for the lamp and control gear combined, to show LCP as it is when installed.
Acceptable information includes independent testing, performed by a NATA lighting laboratory (or equivalent).
Note: The Scheme Administrator will determine if the information is appropriate and acceptable.
3. Asset lifetime
For all lighting using the Commercial Lighting Energy Savings Formula, including emerging technologies, asset lifetime is determined by the Nominal Lamp Lifetime and Annual Operating Hours (as per Table 10 of Schedule 1 of the ESS Rule) as follows:
- if the luminaire, control gear or lamp and control gear are replaced, the lifetime of a product will be assigned the default value of 10 years (12 for road lighting).
- if only the lamp is replaced, or the lamp can be easily replaced with a lamp of higher power, (e.g. for ELV Halogen MR16 or LED MR16 lamps (downlights)), or a T5 adaptor kit is used, the default value does not apply and the Nominal Lamp Lifetime must be determined.
Nominal lamp lifetime claims:
- must be substantiated by manufacturers’ data or independent test reports e.g. showing LM80 results for LED lamps, and
- are limited to a maximum of 30,000 hours.
Voltage reduction units
Voltage reduction units (VRUs) reduce the amount of electrical energy delivered to a lamp once the lighting is turned on, which dims the lamp. The use of VRUs is also referred to as ‘fixed dimming’.
There is no standard reduction in energy consumption that will result from the EUE of a VRU in a lighting circuit. For VRUs to be used in the ESS, the Scheme Administrator must approve a Control Multiplier (as required in Table 10 of Schedule 1 of the Rule).
As part of this approval, details of both the technical details and the operational characteristics of the VRUs and lighting equipment must be provided.
To calculate the Control Multiplier, the output voltage ‘V’ of each VRU must to be specified and appropriate evidence, such as independent testing, performed by a NATA lighting laboratory (or equivalent), must be provided.
The Control Multiplier will be determined asV2/2402.
Energy savings can be significantly affected by the operational characteristics of VRUs. In order to better understand your proposed VRU use, the following information should be provided:
- types of lamps and control gear in the VRU lighting circuit
- the process to ensure that no new inappropriate lighting equipment will be installed that will diminish the energy savings. For example, VRUs connected to lights with electronic ballasts are not eligible because they do not result in energy savings
- the processes in place to ensure that the VRU output voltage setting is not altered if the unit is adjustable and that the bypass switch, if fitted, is kept open after installation and returned to the open position when closed for lamp replacement.
