Nothing like natural light for sure. usually in the dead of summer I have the best amount of natural light in my shop, and I hate when the clocks change making it get dark earlier. I have fluorescent lighting in my shop but I also have those aluminum domed incandescent fixtures with the spring clamps all over my shop with two pointing right at the face of my grinding wheel. personally, I'd pass on those lights you pictured only because of the amount of power their going to consume.
