Adafruit Fiber Optic Light Source - 1 Watt - Red

Light in the fiber optic cable zooms through the core by constantly bouncing off the edge of the molded plastic, a principle called "total internal reflection" (which also sounds like a very expensive meditation island retreat). When the light pipe doesn't have total reflection, you can get a nifty lighting effect from the light illuminating the plastic tubing. All you need is a way to get a ton of photons into your light pipe, and that's what this is! It's Fiber Optic Light Source in a fiery red color.It's a high-powered LED cluster, powered by 9-12V and 100mA of current. The sturdy metal body also acts as a heat sink. Installation is a breeze: simply loosen the clear knob on the LED emitter and slide in one of our fiber optic tubes.Note: This is just the fiber optic LED. You'll also want to grab a fiber optic tube.
