With Spectralight® Infinity, less than 1% of the daylight is lost with each "bounce" of daylight down the tube.  This becomes increasingly important for the winter months, early morning or late afternoon hours, and overcast days.  At these times, the reflected daylight may make hundreds of bounces down the tubing, which would result in minimal usable light output for Tubular Daylighting Devices using less reflective materials (where 8% or more of the light is "lost" with each bounce). However, with Spectralight Infinity, the advantages are clear, over 500% more light output for these normally problematic daylight hours, resulting in radiant, useful daylight in your home or office!
