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.
