This Turkey season I got to my spot before day light with my green lamp on all the way. I could see Deer on the way their eyes lit up green reflecting the light. There were at least 6 and I thought for sure they all would start blowing like crazy. Strange thing was not one of them blew at all,some just stood there watching me go buy. I had never had that happen before they always blew or ran like crazy in the past. All that being said I use a green led if needed pointed down as much as possible directly in front of me and I likewise like to get to the stand at least 45 minutes before dark if it's not to cold out. Some woods are open enough to where light is not needed all the way and most places where I hunt the traails are easy to see with little or no light in the winter. Be safe and do what makes you feel safer depending on where you hunt.
