Sometimes Being Square is Better: Solatube International asks the question “Are you square or round?”

VISTA, CA – 6/16/2016 (PRESS RELEASE JET) — Round versus square. Sharp lines versus curves. The human brain processes each of these differently, according to a Harvard Medical School study led by Moshe Bar and Maital Neta. In their study with round and square objects, they found that most people prefer rounded objects and shapes to sharp-angled ones.* Over the past 25 years, Solatube International has been catering to this majority with its round diffusers. But what about those who prefer sharper lines?

Solatube has finally heard their pleas and now has a square diffuser for residential Solatube Daylighting Systems.

“Part of the magic of our products is the fact that we use a round tube, so it was only natural that we used a round fixture at the ceiling,” said Robert Westfall, president of Solatube International.  “But we now know there are a substantial number of people that prefer squares so we literally had to figure out how to put a round tube in a square hole to accommodate those preferences.”

The key is the patented Spectralight Infinity transition box which takes the round tube into the square hole at the ceiling. The square diffusers are available in both the Solatube 160 DS (10-inch model) and Solatube 290 DS (14-inch model) and are available in either OptiView or Just Frost styles.

Solatube® International Inc., the worldwide leading manufacturer and marketer of tubular daylighting devices (TDDs), invented TDDs (also known as tubular skylights), which harvest and distribute daylight in homes and commercial buildings. Solatube Daylighting Systems are now frequently installed as part of energy-saving and sustainability efforts in residential and commercial spaces in over 122 countries.

Using patented technology, a Solatube Daylighting System harvests daylight at the rooftop, transfers it down a highly reflective tube (which bends up to 90 degrees and can be up to 70 feet or more long) and distributes it evenly into an interior space through a diffuser at the ceiling.

The first Solatube product was sold in 1991 and over 3 million have been sold worldwide to date.

*The explanation for the preference? Bar and Neta proposed that since sharp objects have long signaled physical danger, human brains now associate sharp lines with a threat. Curves, meanwhile, may be seen as harmless by comparison.
