Once you ask this question and start researching you will quickly realize that there are some pretty crazy flashlight nuts out there. Just as opinionated as gun nuts. I bought some off a site in china, Deal xtreme. I know, China is evil, but if you want the best milk, go to a cow farm, best LED's, they all come from China. I have a scope mounted Skyray, and a $20 led headlamp. I made red and amber filters out of light filter paper. These are small lights, and only cost probably $50 for both. The xtreme part is referring to how slow the shipping is. It took about 2 months, so I didn't get to use them last year. I haven't really used them much this year because I haven't had many nights to hunt because of work. But I could easily shoot 250 yards with the scope mounted light, and definitely pick up eyes with the headlamp at that distance. Thats not really how hunting goes here, so the lights are way overkill for the 30 yd encounters. Lots of options out there and I am sure you can get similar lights without waiting 2 months like I did.
