Any film with extended red sensitivity may be an issue and, of course, IR film is out of the question.
    My Spynet thing doesn't fog any non IR film color or black and white. And I've had the illumination as close as arms length. The IR floodlights emit some visible very very dim red light, bouncing off a white wall, illuminates my entire darkroom. I look like an idiot but no one can see me

Not exactly iPhone resolution, but I find it very acceptable. For my use, the 1x magnification is certainly better than the 3x of the 120R, but, again, your mileage may vary. To give you an idea of the field of view, at arms length I can see about 2/3 of an 8x10 film tank and film holder sitting in my darkroom sink. I would like to see the entire tank top, but my arms just ain't that long.

    My only criticism of the 119V, at this point, is that it would be nice to be able to adjust the brightness of the internal screen. With the unit mounted on my head, there is just a wee bit of light, from the screen, that escapes around one side of the eye cuff. At this point, I don't know if it's enough to cause any issue with film, but, since the point was raised that these IR units can fog film, I have two test sheets ready for development. If you're interested, I'll pass along my findings.
    I attached a wide angle auxiliary lens from an old VHS camera I found on Ebay for 5 bucks. My setup has a manual focus wheel. As long as you keep still, it's sharp, I can read "British Made" on my Hewes reels. If you move around the frame rate is too slow to keep things sharp.

    Here's a recording I made with one of my toys, no wide angle

    I tested specifically for fogging because someone mentioned in an earlier post that these IR goggles fog film.

    I sent a email nightfox. Sounds like a nice unit. I look forward to hearing more on how these work.
