Hmmm, i don't think they create hotspots, because I have my top growth less than an inch below the light and haven't had problems.
I think hot spots are only made when the reflective material doesn't diffuse the light that it returns. The inside of the cans diffuse the light pretty well (as opposed to a mirror which doesn't diffuse the light at all).
