Hi @Logan- in my opinion and based on this graph, the halogen is the closest. I use halogens bulbs now as I can’t buy incandescents. Almost impossible to notice a difference.I can find halogen lamps more easily than the incandescent lamps. Do they have a similar spectrum? Can the halogen lamp be used instead of the incandescent lamp?
I believe halogen has a higher orange and a lower infrared, which makes it more efficient than the incandescent. They may be close in the amount of red. That chart you posted is a bit confusing and it's easier to tell on a spectral curve.
It appears the halogen peaks around the well studied nm wavelengths; around 600
Which one of these graphs is true?
This does not ring true to my experience. I am sitting looking at the yellow/red hue from my lights at this very moment. My husband and I compared the blue computer screen to these halogens, NO comparison and simply no blue.Halogen lights contain a lot of blue light and are very dangerous to the eyes.

Halogens see more like natural light than LEDs...
Of course my n=1.

Thank you @schultz! That is helpfulLED's have been getting better, probably because the old ones had such poor CRI scores and looked odd. I think incandescents and halogens both have CRI scores at 100. This is hugely important for the aesthetics of a room (at least for myself). Even if the spectral curve is not necessarily optimal, I will put "high" CRI LED bulbs in the rooms of my house that I tend not to stay in for very long. Bathroom, laundry room, etc. In rooms I spend more time in I put 500w incandescents up for the winter. It's looks very nice and makes it appear like the sun is shining in through the window even though it's grey and dreary outside. I estimate it costs about $30 a month per bulb, so it's not exactly cheap, but one reason is because we are always home (I work from home, as does my wife and my kids are homeschooled...) For myself it's worth the money.
This is a decent LED for occasional rooms, though it is only 1100 lumens so you would probably want several in the room (I like bright rooms).
Here is the spectral curve. Still has a blue peak, but has some nice orange and red in there! I should put like 30 of these in my shop. Might be a reasonable compromise between electricity costs and health... ooooor I could put like 8 of these in

Thank you @schultz! That is helpful
are 60w incandescents useful? i have a lamp with led daylight bulbs in it, should i switch them to incandescent or does it not make a difference at low wattage. btw, i'm not talking about shining the light on me, i'm just asking about being in a room with the light.Halogen bulbs are not so good, they produce to much light in the green wavelengths of 500nm to 580nm, green light still has a lot of blue light charecteristics, Incandescent bulbs produce a much better balanced spectrum of light for healthy cellular functioning.
