With the blueish tint of most typical LEDs it is harder to identify your target than with a good xenon-halogen setup. And the terrain in front of you appears more two dimensional. As far as how many lumens, I would say a steady output of at least 60 lumens is the minimum for a tactical light. It's not really the quantity of light as much as the quality of it though. That said the newer breed of HCRI LED lights are better in this regard. I have one from Malkoff that is fairly impressive. Surefire is starting to get into the game now as well with a warm tinted version of their Saint headlamp.
