This might just be the most novel way to take some LED’s and a lithium battery and put a impressive mark up on them. The HumanCharger looks like a set of earbuds, but it instead of audio it outputs light. Specifically UV-free white light with a 448 nm peak in the blue region. This is known as TBL (Transcranial Bright Light). The claim includes a study that shows using these light buds for 12 minute intervals 4x a day helped people recover more quickly from jet lag symptoms. There is a free Humancharger app that can will link up with TripIt and remind you when to use the headset for optimal flight recovery.
