Lighting in Design February-March 2017

Energy efficient lighting solution complements international brand Busby is a leading wholesale and retail fashion group in South Africa. Busby Retail distributes extensive ranges of clothing, luggage, handbags, accessories, eyewear and footwear, all bearing international brand names, house brand names and private labels. The company is innovative and dynamic which led it to approach Solid State Light- ing International (Pty) Ltd to provide guidance on an energy efficient LED lighting solution that would complement the Guess brand, store location (Sand- ton City) and customer profile while maintaining the quality and efficacy of lighting standards set by the brand internationally. retail brand while falling within the landlord’s shop fit-out specifications, which restricted the specific connected load of the store design to <34W/ m². The right lighting Based on the existing store layout, the SSLI design team used Dialux to model Philips LED StyliD lamps using various combinations of beam angle, CCT and efficacy levels until the right lux levels were met and, in some cases, exceeded.

The Philips StyliD is a breakthrough LED concept combining design, the latest and most innovative LED technology and optical systems, and reliable heat management. StyliD offers substantial energy saving compared to halogen, quality light, complete stylistic freedom, and significant maintenance sav- ings. A mix of narrow and wide beam angles and a mix of 3000 K and 4000 K CCT ensured SSLI achieved the highest CRI possible. Using the StyliD Compact Track Light provided a solution that fell within the landlord’s shop fit-out specifications and significantly lowered the energy consumption and the specific connected load of the store design to <20 W/m².

Customer challenge Traditionally, Guess stores were designed using 70W and 35WMetal Halide lamps to provide high levels of illumination and a high colour rendering index with emphasis on illuminating the products on display. However, owing to stringent changes to the landlord’s store design requirements, aimed at energy efficiencies required for new and retrofit stores, tenants were required to reduce their specific connected energy loads, in particular the lighting solutions used. To prevent this from resulting in a reduction in store light levels, a so- lution was required that would complement the

StyliD offered energy savings, excellent light quality, stylistic freedom, and maintenance savings.
