Solatube International Inc., a global manufacturer and marketer of tubular skylights, announced the release of the next generation of its Brighten Up Skylight Series, featuring expanded design options, enhanced thermal performance and a new size intended to broaden the product’s range of residential applications.
Engineered for superior light performance and long-lasting quality, the Brighten Up Skylight Series combines Solatube’s award-winning Raybender 3000 light-capturing dome technology and ultra-reflective SpectraLight Infinity tubing—one of the world’s most reflective materials—with a newly redesigned delivery zone to bring soft, even natural daylight into any room.
The next-generation Brighten Up Skylight Series introduces several enhancements designed to give homeowners more control over how daylight fills their homes. The series adds two ceiling fixture collections, ThinLine and Contour, offering distinct design profiles and diffuser options to suit a variety of interior styles. It also introduces the 290DS Plus (21-inch diffuser) model for larger rooms and vaulted ceilings and ComfortSeal Technology, a redesigned ceiling interface with integrated seals and stackable lens options to improve thermal performance and energy efficiency.
ThinLine Collection
The ThinLine Collection features ultra-low-profile fixtures that virtually disappear into the ceiling. With a profile up to 70 percent thinner than previous designs, ThinLine delivers balanced, soft daylight that gently fills the room without drawing attention to the fixture itself. Diffuser options include SoftView, which provides a wide-spreading, glare-free pearlescent glow, and OptiView, a crystal-like Fresnel lens that creates a subtle “view of the sky” effect. All diffuser options are available in round or square designs to suit a variety of interior styles.
Contour Collection
The Contour Collection delivers a sculpted, dimensional look to ceilings, combining form and function. Diffuser options include JustFrost, a layered frosted design for soft, diffused light; TierDrop™, which spreads daylight through cascading contours, creating a refined ceiling halo while spreading light throughout the room; and OptiView Frost, which merges Fresnel optics with a wider frosted layer for a bold architectural effect.
290DS Plus (21-inch diffuser)
Building on these design options, the Brighten Up Skylight Series also introduces the new 290DS Plus model, engineered for larger rooms and soaring ceilings. Featuring a 21-inch diffuser, this fixture provides a more dramatic ceiling presence while delivering soft, evenly distributed daylight, making it ideal for spacious living rooms, kitchens and vaulted areas.
ComfortSeal Technology
Designed to maintain indoor comfort and energy efficiency, ComfortSeal Technology features a redesigned ceiling interface that reduces air transfer and enhances thermal performance. With four integrated seals and the ability to stack the new ThermoLens options, this technology helps maintain consistent indoor temperatures year-round while ensuring daylight remains soft, even and comfortable. This advancement underscores Solatube’s commitment to delivering daylighting solutions that combine superior light quality and incredible thermal efficiency with practical home comfort.
