You would probably have to put stage lighting in your house to get the same affect as being outside. My eyes behave pretty different and seem to get a "workout" when I am outside in sunny weather.
But regarding the lighting itself, yes i do think it is similar to stage lighting (brighter, i assume). Thermal and power is a significant concern with the lighting iirc, but i'm not too familiar. If i recall correctly the post that advocated these as a video and had an explanation on the difficulties. It heated up the room significantly.
With that said i want to stress that this was some post i saw several years ago, and i can't seem to find the video anymore. Iirc the lights were insanely bright, though.
