Certain insects are attracted to IR, especially spiders, or so I am told here in this forum. I personally have never researched this. But I will say that the only cam I have using IR is in my back yard and it is the only cam that has bugs gathering around it. But, I do not have any cams with LED lights on them, so maybe that would attract bugs also.
There are bugs that are attracted to white light, such as moths, June Bugs and the like. I see them pounding into my couch lights at night. But that does not impact my cams as the lights are not right next to my cams.
Asking what you should get, LED version or not, is not going to help you. Only you know your own specific situation, how much light you have available, location of the cam, etc. Ultimately it is you that has to decide. Asking folks that have never been to your house, that live 1000's of miles away, to make your decision for you is not the best thing to do.
