What lamp do you usually buy to avoid UVC but with a good spectrum in IR?

UV-C won't pass the glass envelope in any meaningful quantity. Not unless the glass has been engineered for it (sterilising mercury lamps). UV-A does, but that's not a bad thing. IR is present in a very broad spectrum. Glass, even cheap sodaglass, has good near-IR transparency.
You dont get uvc from incandescent. To get uvc from a fluorescent (mercury plasma) bulb, you need it to be void of phoaphor and made with a quartz tube. Otherwise, UVC is only present when you are in proximity to welding. Uva and uvb are what you get sunburn from, and what gives you that unpleasent tingling when you're in direct sunlight at high-noon. Its best to avoid direct sunlight mid-day and stay in shade amidst greenery, because Rayleigh blue-scattering is minimized at that time of day.

Yes I know. I deliberately use mercury plasma to create disinfection lights. I was speaking about the metal halide lamps. I could not find the spectrum of any but some that are sold as full spectrum specify that people should not spend there more than few minutes because of the UV. So the question is. Is there one or more full spectrum minus UVC on the market, not for plants only.

Some specify of the dangerous UV emission because they are for growing plants. Are there some specific brand and model that have a full spectrum from deep IR to UVB with no or little UVC and a spectrum similar to the solar one?
