Sun Tunnel Light
Crystal 200 and 400 Base Kit
Features
(Sun Tunnel Light)
The Crystal product line is unique because of the use of a glass roof dome. It is made of Bohemian crystal glass and it practically doesn’t get old. Compared to a plastic dome, it is resistant to aging, even with a barrage of UV light. The crystal dome will not yellow or discolor over time like plastic, therefore it's sunlight collection performance will stay the same for decades.
The crystal dome will collect daylight even if it is cloudy and it won't distort natural daylight colors.
The surface of the crystal is very smooth and hard therefore smog, dust particles, or other impurities in the air do not cling to it, which means it needs almost no maintenance.
The Lightway Crystal collection is produced in two sizes: 200, 400.

Reflective Pipe:
The inside surface of the pipe is coated with a pure silver finish using a vacuum coating technology that provides very high total reflectance and excellent coating integrity, durability and U.V. resistance. The reflective layer is guaranteed not to crack, peel, or be warped by changes of temperature and humidity as well as long term exposure to UV. Connecting the pipes together or to the adjustable elbows, Blue Performance, dimmer, and ceiling diffuser is easy thanks to custom designed connection hardware, which come standard in every kit.

- 98% reflectivity inside pipe with minimal scattering
- 99.9% pure silver coating
- Join pipes together to conduct light throughout buildings
- 24.6" (625mm) long sections

Adjustable Elbow
The adjustable elbow has an angle range of 0 - 45 degrees. It is used for custom routing of the reflective pipe without sacrificing light transmission. The adjustable elbow is easy to connect to another elbow, a pipe section, Blue Performance, a dimmer, or ceiling diffuser. The elbow is made from the same highly reflective and durable material as the pipe.

- Change directions and route the tubular skylights throughout buildings
- Available in 0 - 90 degree option for LW 600

Ceiling Diffuser:
The glass ceiling diffuser is an important component in the tubular skylight that not only diffuses and equally spreads light in the room, but also becomes part of the aesthetic design of your interior. This high quality diffuser is made of glass, which doesn’t age or turn yellow and transmits the light without color change. The ceiling diffuser easy connects to an elbow, pipe section, a dimmer, or Blue Performance.

- Integrated gaskets to prevent air leakage

Blue Performance:
The Blue Performance insulation element prevents thermal transfer through the tubular skylight system. This is a very important component and one that is highly recommend for any location that experiences a large temperature difference between indoors and outdoors. Not only does Blue Performance save energy by preventing heat transfer, but an even more critical feature is that it prevents condensation formation inside the tubular skylight pipe and ceiling diffuser which could lead to dripping water and damage to your ceiling. Condensation is a phenomenon which almost everyone is familiar with and Lightway has a unique and perfect solution for the tubular skylight. Blue Performance is easy to connect to elbows, pipe sections, a dimmer, or ceiling diffuser.
