S3 E3 The origin of using Blue LED Light on Comics by Joseph J. Topczewski, Phd. This video discusses the origin of using 450-460 nm Blue-LED light for the purpose of comic book stain removal and whitening. We acknowledge it isn't the first time the light was used for cleaning teeth, toys or game systems. This is about using the blue light waves on comics and paper. We address the misconception that Blue LED (450-460 nm) is UV light (defined as wavelengths between 100 nm and 400 nm). We offer a simple explanation on why these lights work so well.
