Comments about Bosch EX12LED-3BD-9W Black Diamond Infrared Illuminator (940nm, 60 Beam):
This is not a 12 LED illuminator as the name implies, but only 3 LED. Also, the 3 LEDs glow a visible red, which 940 nm LEDs should not. I returned the first unit to Bosch, and they sent a replacement, which also glowed red. After a few rounds with tech support, they told me the new surface mount 940nm LEDs glow red, but not as much as the 850nm.
Well made housing though, and it basically works - just is not really 940nm light as it is advertised to be.
