Skylights admit an overwhelming amount of sunlight. In the past, homeowners often complained that skylights were perhaps too much of a good thing. That was largely because furniture-fading UV rays would piggy-back alongside the desired natural light. To combat UV rays, the Solatube Daylighting System employs safeguards in two places: the roof dome that harvests sunlight, and the reflective tube that channels the light into the home. Where the tube ends, a diffuser (which looks like a standard light fixture) takes over to ensure even, glare-free lighting throughout the day.
