The groundbreaking SkyVault Series gives you ultimate daylighting control. By mixing and matching components, you can enhance light capture, control the focus and create dynamic designs in large volume spaces with high, open ceilings...all with just one system.

  • Delivers more light to meet illumination requirements
  • Provides maximum output with minimum impact on building envelope
  • Can be tailored for specific project needs
  • Reduces installation costs


Color consistency

The SkyVault Series features high Color Temperature Maintenance, or CTM. This means the daylight color remains white and won’t shift, offering stable color rendition of the visible light spectrum over the course of the year.



Light output

Unrivaled Light Transfer Efficiency, or LTE, enables the SkyVault Series to deliver maximum light throughput. The result is better quality daylight with greater output, so light can travel longer distances without losing intensity.




Design flexibility

The modular SkyVault Series functions using a “mix and match” concept. Optional components that enhance daylight collection or adjust light focus can be easily attached to the core unit. In this way, any project need can be met with one system.




Built-in savings

A revolutionary Tab-Lock Connection System with Tube Belts makes it easy to install the SkyVault Series. Without screws or tape, materials and labor are minimized. Nested components and minimal packaging also reduce waste and shipping costs.

Advanced optics

The SkyVault Series selectively delivers the visible spectrum of light while filtering out damaging infrared and ultraviolet wavelengths. This reduces daytime cooling loads, prevents interior damage, and minimizes glare and shifting light patterns.


Thermal efficiency

The SkyVault Series comes with built-in temperature control features. A pre-assembled insulated (R6) and sealed curb cap, Spectralight Infinity material, and optional dual dome all combine to minimize heat gain / heat loss and optimize thermal efficiency.



Affordable sustainability

Using sustainable natural daylight, eco-friendly Solatube products provide energy-efficient lighting that cuts electricity use. This reduces environmental CO2 emissions, minimizes a building’s carbon footprint, and saves money..





Engineered reliability

We engineered the SkyVault Series for easy operation and long life. Sealed, pre-assembled top and bottom assemblies, self-cleaning domes and UV / IR filtering ensure high-quality, high-performance daylight delivery with zero maintenance required.

SkyVault Series Amplifier

The Solatube M74 DS Amplifier significantly improves the delivery of daylight in high bay and high ceiling applications. Featuring 36 highly reflective facets made of proprietary Spectralight® Infinity material, the cone-shaped amplifier:

• Reorients daylight to the visual task plane in occupied areas

• Converts daylight at inefficient angles into useable light for increased optical efficiency of diffuser technologies


SkyVault Series Diffuser Assembly

SkyVault Series Diffuser Assemblies provide precise control over daylight collected by our optical domes and Spectralight Infinity Tubing. Each is factory-assembled to make field installation quick and easy.

The  Diffuser Assembly comes pre-assembled and easily attaches to extension tubes using the patented Tab-Lock Connection System and Tube Belts. The circular shape is designed for open ceiling applications and the Prismatic lens delivers maximum daylight to the work floor.

Extension Tubes

Extension tubes feature a revolutionary Tab-Lock Connection System with Tube Belts that prevent gaps and eliminate the need for screws and tape. Tubes come in 24 in. and 48 in. lengths.

Optional Security Guard

The optional Security Guard comes pre-installed in specific dome assemblies and consists of a stainless steel rods welded into a hexagonal grid riveted into the curb cap turret, creating a visual and physical deterrent at the dome level.
