The story kinda makes me worry if that's the real story. Between the lines, I read the guy's using grow tents. Many people do. Some do have a foil-like interior. The story says Halogen, but how many reporters can tell the difference between Halogen and MH/HPS - all they see is bright light.

100F is hot but not really hot enough to kill someone. Make them uncomfortable - sure.

Now wasn't some tent manufacturers having problems with their tents giving off gases that was killing plants? Could it be maybe this poor guy didn't have proper ventilation, and gassed himself to death. To me, that's more plausible.
