OK, so we now have a bunch of hogs moving in about 1 AM and I need to get rid of them. I have a spotlight setup to make the night into day, but was wonder about the green and red lens covers that are sold. I know that they are there to not spook the hogs into running like the main clear beam would, but which is better? I have seen both used and my spotlight came with a red lens cover. I see that the The Kill Light Portable Hog Light System (as seen on another post) uses green LEDS and other Varmint light systems use a red cover. What are the optinions on the red vs green lens covers?
