  [Aroid-l] Philodendrons produce infrared light???

I expect that what is being described is infrared light radiating from
internally-produced heat via thermogenesis. Thermogenesis will happen in
the dark. Warm bodies radiate infrared. You, sitting at your computer
screen, are generating infrared just sitting there and being alive. That's
how you feel warm when there's a fire across the room. The amount of heat
emitted by a body depends on its temperature and will radiate energy even
when quite cold, although it is not as easy to detect. The earth radiates
stupendous amounts of heat into space all the time.

Yes, an infrared camera will pick up a glow from an aroid "in heat".
