FEATURE LIGHTING & CONTROLS NAVIGATING LIGHTING STANDARDS
Lamp and luminaire manufacturers must meet the rising demand for energy-saving lighting products alongside rapidly evolving regulations and energy labelling requirements
In Europe, designers and engineers
should look for the CE marking on lighting products. This is a manufacturer’s or importer’s self- declaration that the product conforms to European requirements. Such a product should come with a Declaration of Conformity that states which standards the product has been tested to. Depending on the outcome of the

hile there are similarities in global regulatory frameworks,
there are subtle variations in the conformity assessment process between countries and a lack of international harmonised standards for energy-efficient lighting products. Directive 2009/125/EC, also known as
the EcoDesign Directive, is the primary regulatory instrument in the EU regarding all energy-using products. The Energy Label Directive (2010/30/EU) complements this by providing a framework for requirements regarding labelling and other means of providing end-users with product-specific energy consumption information. The EU Ecolabel is a voluntary product certification which helps consumers to identify products that achieve the highest levels of energy efficiency. In the UK, the Energy Saving Trust
operates a voluntary product certification scheme for energy-saving products, with compliance verified through an independent third-party test report. BREEAM is the UK property industry’s
recognised benchmark for the environmental rating of new and major refurbished buildings. ‘Innovation credits’ provide additional recognition of a development in the field of sustainable performance. Our lighting specialists have worked alongside other disciplines to produce a credit checker, which gives everyone involved in a project the complete picture of credit targets to ensure that environmental ratings are achieved. Energy efficient lighting product
programmes vary significantly across the world. For example, in Canada the Energy Efficiency Regulations require that all

lighting products manufactured, imported, or sold must bear the energy efficiency verification mark of an accredited certification body. Certain types of lighting products must also display a lighting product label that includes information on light output, energy use, and expected product life. Likewise, the USA’s ENERGY STAR is a voluntary testing and labelling programme which helps consumers identify products with the highest levels of energy efficiency. Minimum standards for LED lamps in
Australia and New Zealand have been introduced in line with EU standards. The phase-out will remove remaining incandescent and a range of halogen lamps from the Australian market, where an equivalent LED lamp is available. The timing of the new regulation will align with revised EU minimum standards that will apply to LED lamps (planned for September 2021). Choosing suitable lighting products Energy efficiency is now a key feature
of any lighting design as schemes must meet the latest criteria. However, there are many other important reasons for implementing energy efficient lighting innovations. This ranges from the more obvious reduction of power consumption, to benefitting from incredibly low- maintenance requirements and associated costs. As LED costs continue to fall, so sales of
them are on the rise. However, the range of available energy-efficient luminaire products and lamps can be overwhelming for the designer, as the market for these products has undergone profound changes in a very short space of time.
ongoing Brexit negotiations this year, UK lighting manufacturers may have to replace the CE marking with a new ‘UK Conformity Assured' symbol, for the British market. UK lighting manufacturers will still be able to sell products that have been made and assessed against EU regulatory requirements and which carry a CE marking, for a certain transition period. High-efficiency lighting technologies
offer up to an 85 per cent improvement in energy efficiency compared with conventional lighting technologies, while providing an equal or better quality of light. However, implementing energy efficient lighting into a well-designed scheme can be a complex procedure, as the lighting designer must ensure that efficient luminaires are used. This makes it necessary to think about the design in its entirety, both creatively and technically. For example, it should cover the downlight, the associated drivers and the lighting control system. The design options are endless, as LED
technology is changing so fast. LED light sources are becoming brighter, smaller and more efficient, and double height spaces can now be illuminated to the required lux levels from the smallest of luminaires. Leading lighting manufacturers are also producing ever- improving optical systems for luminaires, which is increasing their efficiency. While the introduction of more efficient
lighting technologies has resulted in considerable energy savings around the world, new lighting technologies also create ever-changing regulatory compliance challenges for both manufacturers, designers and end-users. With all of these regulatory considerations, product choice variables and other technical considerations that must be made, the design process should be started early within the building development plans.
