Correct and an LED requires very little current to operate. Sounds like she hasn’t invented anything new but may have found a way to apply current technology to meet a need. We’ll see...
We use LED lights in some of our USAF planes for general lighting (To save energy I suppose), It sucks, it is crappy lighting and there are some big ass jet engines sucking some fuel out there so what is the point?.
OK I get reducing the power load so we have more capability.
Hey, you gotta pee standing up in the corner at 50K with a curtain around ya, because some ahole bitched about a $900 terlit seat LOL.
All this stuff is a trade off.
