Reflective Tunnel Skylights

[HighOnPottery]

I am wondering if anyone has ever attempted growing under those compact skylights. It seems like a good idea for keeping a stealth operation indoors using the sun. With old skylights the light moves around according to how the sun is positioned, but these shoot straight down, and they're really bright. The install only requires a hole cut in the roof and a hole in the ceiling and some weather proofing on the roof. I've installed these before and that's what intrigued me. Maybe one could shoot one down into a closet lined with mylar? You can get one of these for like $350 put two in a closet and maybe you'd be better off.

We need to know how many lumens in one of those, I suppose.

I've been interested in these for some time, and I've seen them at Home Depot. Definitely would be a decent amount of work to cut a hole in your roof and ceiling, but I'm betting that they would work quite well in a relatively sunny location. Maybe too well.
