I'd like to know if anyone has experience of either of these. Critically do either show any visable light? Are there any good sources for quality non visable IR filters/leds?

cuz that's the name of the thread title...?Why would he have to use LEDs?
Because that was the what the question in the OP was. He wanted to know which source IR LEDs or IR filters produced no visible light.Why would he have to use LEDs?

So he asked if IR LEDs or IR Filters produced less visible light?
You can't put an IR filter on an LED because IR filters filter out everything but the IR.
Non IR LEDs don't produce enough IR radiation for a filter to work.
Therefore, you have to have an incandescent to use an IR filter. Therefore to break his question down in a logical and realistic fashion, what he is asking is:
Do IR LEDS or IR filters on an Incandescent produce any visible light?
It depends on the quality of the product you buy.
I can only speak for SureFire IR filters on a SureFire weapon light and did not see any visible light.
I can say that I know plenty of tactical teams using SureFire IR filters in conjunction with NVGs. The sheer number of them in use should speak for itself.
Never seen an IR LED so someone else will have to comment. I've seen members with a SureFire M1 and they should be able to tell you. I think it was Defabricator.
Or you could use a cheaper IR LED, and filter out the shorter visible wavelengths to make it completely invisible to the naked eye, and you would STILL be more efficient than filtering an incan source.
