The whole way of thinking about light will change.
The 660 lumens are spread in all directions while the LED is focused, so that the intensity of the light is much greater. The characteristic of LED lighting is that it only lights what needs to be lit -- and not everything else around it.
It's like the power of the laser; it only cuts what it touches -- leaving everything else untouched. It turns light into a precision instrument instead of the crude one the Edison bulbs represent. That's why we need to make a leap forward.
We're heading in this direction in all aspects of our lives. Even space can be optimized so that a person can live and work in a very small area, with only a few tools -- like a laptop and cell phone and be an entire industry.
The most basic of tools is the light wave/particle.
