In my experience, Halogen seems to come closest to the warm calm of natural sunlight. Seems like this article helps to confirm that. Been trying to find the best halogen in an A19 bulb form factor so I can deploy them all around my house. So far I have come up short and the best I can find is Halogen floodlight which is just not the same.

Maybe I should just give up and install a bunch of these "sun tunnels" in my house.
