Leds can output 275nm-950nm. IR is between 780nm-1mm. These aren’t exact numbers. Probably something in that overlap was damaging them somehow. Or it might be something totally different and the person had misdiagnosed. What I’m uncertain of, is if the led is intended to produce a certain color (white, blue) how much it would be emitting on the IT spectrum.
