I'm sure this has been asked here many times, but I don't quite have access to the search feature. Being completely new to modding flashlights it's kind of difficult to keep up with some of the language thats being used in the posts. I'm looking for something that will give me a nice red beam at 200+ yrds, 400+ lumens . I've seen some mention and aspherical lens that they have placed in their lights, where are you guys getting these from and how much of a difference does it make? If I were to get a "host" light, which would be best to start off with and which red led would I replace it with? Thanks in advance for everyones help!!
