How can Solatubes products bring so much daylight into the room?
The reason for this astonishing claim, is the ultra-high “specular” reflectance of our tubing materials! With the advancement of Spectralight Infinity, less that 1% of the daylight is lost with each “bounce” of daylight down the tube! This increase in reflectivity (and, therefore, the skylight’s efficiency of light transmission) becomes increasingly important for the winter months, early morning or late afternoon hours, and overcast days when a significant amount of the useable daylight is coming from low angles of the sky. At these times, the reflected daylight may make hundreds of bounces down the skylight’s tubing, which would result in minimal usable light output for skylights using the older tubing 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!
