Adafruit Fiber Optic Light Source - 1 Watt - Green

This is a pretty neat way to glow up. Light in the fiber optic cable zooms through the core by constantly bouncing off of the edge of the molded plastic, a principle called "total internal reflection" (which also kinda 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 a Fiber Optic Light Source in a seafoam green color.It's a high powered LED cluster, you need to power it with 9-12V and 100mA of current, the metal body acts as a heat sink. Then, installation is a breeze. Just loosen the clear knob on the LED emitter and slide one of our fiber optic tubes.Note: This is just the fiber optic LED. You'll also want to grab a fiber optic tube.
