I have ordered my ir led strip from NEONICA Poland, they sent it to me, but with no info about the wavelenght , so after enquiring them by email they told me that the led strip they sent to me is 940 nm.
Is it normal that 940 nm ir led strip emits red light ?
I can see the red dot light in the center of the leds even if i have the light on in my room, or in cloudy daylight, and if i direct a led flashlight to the led strip i can not see anymore the red dot light on the ir leds.
I was supposing that the redish light on the ir leds can be seen only by night, and on the lower wavelenghts like 720 nm or so.
I need to order the filters and i do not know if this is normal or they sent me something else than 940 nm led strip
Redish ir led strip is this ok ?
