 | Daylight Dimmer™
Because you don’t need 100% of the light 100% of the time, the innovative Solatube Daylight Dimmer easily controls the amount of daylight entering a room with the convenience of a switch. Our patented* variable butterfly baffle controls the light output. Accepts power supplies ranging from 90 to 277 volts AC.
* Patent #7,082,726 | | |
 | Secondary Diffuser
To eliminate unwanted glare or to reduce light output, an optional secondary diffuser can be inserted into the Solatube® Daylighting System dome for natural lighting preference. | | |
| Spectralight® Infinity Extension Tubes
Extension tubes can be added in increments of 24 in/600 mm for long runs without sacrificing performance. Spectralight Spectralight Infinity has the highest reflectivity in the world for the brightest, purest light. Create tube runs of up to 50ft/15m. | | |
| Flashing Turret Extensions
Use to raise the height of the Solatube dome on a roof to avoid snow, water, or shading from roof obstructions. Order additional Spectralight® Infinity tubing to accomodate turret height. Available in 12 in/300 mm, 24 in/600 mm, 36 in/900 mm and 48 in/1200 mm sizes. |  | | |
 | Transition Box
The Solatube 21-C features a patented transition box that seamlessly converts the round tubing to a square diffuser. The transition box easily fits into standard commercial ceiling grids. | | |
 | Flashing Insulator
This insulating material helps to reduce flashing condensation in cold climates when the flashing is exposed to a humid interior space. The insulator is affixed to the flashing base and the top tube slips through the opening, which provides a seal between the interior and metal flashing. | | |
 | Open Ceiling Trim Ring
For use with the Solatube 21-O, the trim ring provides a finished appearance to the installation. | |
|
| Daylight Dimmer™ Switch
Daylight Dimmer Switch Kit includes DPDT switch, wall plate and 15 ft/4.5 m of cable. Multiple Daylight Dimmers can be controlled by one switch. | | |
| Security Bar
This stainless steel bar inserts into the flashing turret across the diameter of the
opening. The bar is fastened using rivets and prohibits entry through the dome. | | |
| Dome Security Kit
The kit consists of six rivets with protective nylon spacers, which replace dome
screws. The dome security kit reduces the possibility of the dome being removed. | | |
| Wire Suspension Kit
Use the wire suspension kit when additional bracing to the structure is required. | | |
