Advice sought, looking for infrared LED light.

Unless I am mistaken you will not be able to see infrared. The lights you have listed are just red leds or a red filter and will work just fine.
 
My experience is that you can see ir with either passive or starlight night vision. An IR flashlight is useless to the naked eye. You may be able to see IR with a video camera. and a filter.
