Dimmer with Remote
dimmer allows you to adjust the amount of daylight entering a room with an easy-to-use remote control. Perfect for any room that may need to be darkened during the day including bedrooms, media rooms and conference rooms. Available for 10″, 13″ and 21″ models.
Electric Light Kit
The light kit adds an electric light fixture directly into the Sun Tube for night time use. It can replace a previous light fixture or it can be installed anywhere with additional electrical wiring.
Elbows & Sun Tube Extensions
All kits come standard with 4′ of light pipe. Additional 2′ extensions are also available and can be trimmed to your desired length. On some installations, it may not be possible to install a straight run of light pipe. For those installations, Columbia offers an elbow adapter constructed out of the same highly reflective material as our light pipe. Elbows are fully adjustable from 0 – 45 degrees allowing you to skew the direction of the light pipe to avoid attic obstructions.
