LED modules for accent lighting surpass the performance of halogen lamps (MAGAZINE)
Modules built using separated phosphor technology demonstrate that the benefits of LEDs can be harnessed in the realm of accent lighting with no compromises in light quality, even taking halogen as a benchmark, as ROGER SEXTON describes.
In the 1970s, the advent of dichroic halogen lamps allowed high-quality accent lighting in retail, hospitality, museums and other applications. From the 1990s until now, compact metal halide lamps have also been used in these applications offering more “punch” (for example, highlighting of merchandise even against the higher background illumination levels of department stores) alongside improvements in longevity and energy consumption.
At the beginning of this decade, highbrightness LEDs showed the promise that more improvements still could be made in terms of longevity. However, until now, light output and efficacy, luminaire size and light quality compromises have been barriers to adoption.
