Test comparing IR Beacons, DIY versions of "Budd Light" model, that sits directly on top of a 9V battery. Viewed from the side, theyre both pointing upwards, 850nm vs 940nm, although 850nm do have a bit more current, the increased sensitivity in Gen1 and Gen2 image intensifiers for 850nm vs 940nm light makes 850nm much more visible. You can see two small faint red dots on the 850nm if looking directly on to the beacon at about a meter or two, but not from the side. Intended for marking stuff in Airsoft games.
