USB light bulb

Apparently the next generation of USB technology will have enough power capacity to run a laptop.

Right then is when I want USB plugs discreetly scattered all over the house, some at head height, some on the ceiling, and some near the ground.

I wouldn’t mind the option of plugging in little USB light fittings with the option to change the look over time.

I would see the USB plug not only providing the power but also all the mechanical attachment requirements.

You’ve seen those USB plug in lights for laptops and kindles. Just imagine a range of properly designed house lights that could be plugged in 

No need for down lights then.
