Idea – USB Portable Led Lightbulb

The idea is simple.

I wonder. To make it very cheap for those without electricity. Why not separate the battery and the light source.

Making the light run on usb power would mean that they could run it with any powerbank they can afford.

Maybe this can work as emergency lights also. Here you only need a powerbank for the lights and your phone.

So the idea is that there should probably exist usb powered lightbulbs, lanterns and flashlights.
