they are made by ipower. the lack of drag in these makes me think this would actually be quite a good design and effective.What is the make/model of that reflector?
Not sure about that design. Most quality reflective material is expensive, so manufacturers just add a sheet, and don't make the whole thing out of this material.
The cool tube design works, but the reviews I have read on leading cooling reflectors don't have a tube (which I found that surprising).
What is your budget?
