that’s only true if you shine it out a very large the window
The visible part of the spectrum is likely going to be absorbed somewhere far away from the place you’re trying to heat up. Also, I’m not educated enough to tell if there will be further losses of energy

If it’s in a room the visible radiation will still just heat up the room. If you’re using it outdoors and point it away then yeah you’ll have some waste.

Not sure if visible radiation that leaves through a transparent window will still heat up only inside the room, that what I meant. Probably should have phrased it better
