Very curious why you want to avoid LEDs

You can buy IR and UV leds. All high end grow lights have these for plants. Low quality cheap led products won't include them but that is nothing to do with LEDs themselves that is just consumer preference and price conformance.

I just use a few incandescent lights in every room to fill the “blancs” of LEDs spectrum
