Looking for a "reasonably priced" light for my DPMS Oracle. I've read a &%#-load of stuff on lumens and candelas, etc and have passed the thoroughly confused point. My primary use will be in and around the house and out to 50-75 yards. I think I need something with two selections for brightness, one for in close and the other out to my distance.......with particular concern that the low level setting is not too bright for inside. Can someone sum it up for me please? Suggestions or thoughts appreciated!
