Yes, they probably do, but for none of the reasons you think or have stated.
The insulation of a house prevents roof/wall detection unless it's an obscene amount. No plants could survive the environmental conditions to produce such spots on walls or roofs.
Sound is not electromagnetic radiation(light). Sound requires a medium to travel though, light does not.
Both are waveforms, light is also a particle(photon). Waveforms which align phase amplify one another. If you have two times the amount of light particles... that's also two times the...
You're good for about a year. At which point HPS is around 80% lumen output. MH, you'd be down to about 70%. MV, even less(only bulb here with both *usable life*, and rated life expectancy before failure).
After 1 grow(under 6 months) it's likely still pushing out over 90% of the 'brand...
You can get an extension cord for around a buck at most stores. And a plug-in socket for about $2. Makes the socket on a cord($6) seem like a total waste of money(100% mark-up).
Cops have field test kits that can determine if the resin is from weed.
If the pipe has been properly cleaned(no resin) there is nothing to test. It's as good as new.
High fructose corn syrup is also in everything.... Nasty stuff. Most comes from genetically modified corn. Bunch of various arguments about the detriments of consuming GMO foods.

Pretty sad, we should definitely...
Please supply the time stamps of the instances. I was doing what you just said, the roofs appear to always be solid pitch black. There does seem to be a sky light(window on the roof) on the house he finally shoots himself at(the large grey rectangle on the roof).
Glass is nowhere as good of...
