I also know that coyotes can see the glow of the emitter. So doing lots of reading I found they make different wave lengths of Ir Illuminator bulbs. And also I think skypup mentioned briefly about a lazer Illuminators that have no glow.
Do you guys have a list of Illuminators that give the least amount of glow?
These mutts get pretty cagey to the glow of the Illuminators. Currently using the original torch from TNVC

On our Torch MKII we also have 2 drop in diode heads at 880nm and 910nm. No need to purchase a whole new unit, just the heads you need. Thank you.
Vic,
Does one wavelength have a better “throw” than another, or does the difference in wavelength make one more visible through NV?
The WL has to do with modern Gen 3 devices and a balancing act. Gen 3 NVD's see their best from 650nm up to 850nm and anything above 850, they start to lose their sensitivity in a hurry. At a 940nm IR LED emiiter, the visible light is VERY dim at the diode and also much less sensitive in the IR to Gen 3 devices.
Our Torch Pro using a 880 diode (with dim vis glow) will reach 250 yards+ while the 940nm Diode (with virtually undetectable glow past 10 yards will reach 150 yards. Of course, these are based on very dark environments, with no moon, etc.
There are other ways to cheat the visible glow from IR emitters which we use in our design and that is how deep the emitter sits in the head housing itself. I feel our units along with Surefire do this the best to mitigate this visible glow. (**Note** We build and design these with the heads, glass, and the electronics in Germany and the housings in the USA). These are not Asia made lights made for us in any way and you will not see any "other" variations of the Torch Pro MKII out there).
Another way to mitigate IR glow is not to use a reflector but a lens system which we use along with Surefire systems. We sacrifice some spill this way even though our super smooth rotating bezel will get you up to 12 deg to 300 yards and down to 3-4 deg for 800 yards. The Streamlight Super-Tac IR is great wide flood unit that rocks, but is also using a reflector to get this super flood, but it comes at a costs as one the most brightest visible red glow units out there that can be seen naked eye at 150 yards +.
Hope this helps a bit...Thank you.
