Short YouTube clip (creator: Shereene Idriss) examining whether barcode/CCD scanners can function as red-light therapy devices. The speaker explains barcode scanners use a single LED reflected by a mirror and concludes a single LED is unlikely to produce meaningful therapeutic effects, contrasting this with a commercial LED device (Saluma) that contains over 300 tiny LEDs; speaker states no affiliation.

You see that I'm good enough. She might actually be on to something. Let's look into it. What's insane is that there is actually an LED light inside a barcode scanner. This is called a CCD scanner that emits a light reflected onto a mirror, and that's why it looks like it's covering her whole face. The real question then is, is one LED light enough to really give you the effects that you're looking for? And the answer is no. You can spend all day with that barcode scanner all over your face, and you're probably not going to get much effect out of maybe if you have a zit and you let it sit. Who knows? However, if you're looking at a real, reputable LED device, like a Saluma, for example, and I have no affiliation with the company that has over 300 tiny little lights in the actual product.
