Bringing sun indoors

3M India's Architectural Markets has developed a sustainable new lighting system '3M Tubular Daylighting Device' which effectively transports sunlight from the roof into interior spaces while cutting out heat, glare and radiation. The core of the device is made of a 3M material that possesses high reflectivity, minimal loss and negligible colour shift - even in cloudy conditions and has the highest visible reflectivity, ie, over 99 per cent. Its unique lens design reduces glare, eliminates hot spots and does not alter the colours of the transmitted light. This LEED compliant system offers a payback period of 3-3.5 years.
