Yes, the light is very white (with the right LED). Brilliance has been the issue, but it is improving.
If it were not for Air Conditioning, I could live comfortably “off the grid” where I live. With a combination of wind turbine and solar panels, it is child’s play to do that now. The hurdles are washing clothes, air conditioning, and power tools. You can cook, heat, and heat water with gas. I have had some thoughts of installing such a system and replacing a few appliances with versions that will run on 12-16 VDC. At this point it is simply not worth the effort, but it can be done.
If Cap & Trade were to pass, I might re-consider this. I already have 3 solar panels and permanent magnet wind generators are not expensive. Batteries are another issue.
Before REA came to rural Texas this is what my grandfather did. He had a wind generator and battery system for lights.
Permanent magnet wind generators (alternators) are very efficient now, unlike the old ones. And require very little maintenance.
How is the heat treating you this summer? Stiffling isn't it.
