And if so, are they near-infrared, medium, or far-infrared, and how much of each. I am talking about those 250 watt bulbs sold as infrared bulbs, for warming arthritis or whatever.

As you can see, they are dark red and so emit a small amount of visible red light and then of course, near infra-red (immediately adjoining the visible portion of light).

Near infrared.

No they are not "true infrared light" bulbs. They are actually radiant heat light bulbs.
Radiant heat is a source of heat that does not heat air molecules, but rather heats objects in a room. This is why they are good for warming our joints.
A room heated by radiant heat will have "solid objects" warm to the touch, IE. walls, floor, furniture.

Is the fixture you're making use of rated for a 150w warmth easy bulb? a conventional 150w bulb runs cooler, so as that they are no longer precisely interchangeable. in the journey that your fixture is meant for warmth lamps you have to be ok. A warmth easy fixture could have a porcelain base. If the backside is plastic, use a different fixture.

Mostly "near IR"...look at the side of the box, there is often a diagram of the spectral output.

Check with the co. that makes it I am sure there is a spectrum ,info on them.
