I'm about to travel overseas in a few weeks for a period of under a month. I'd like to take with me a LED or Incadescent flashlight of some sort. What's all the rage now adays and something that comes highly recommended? LED or Incadescent? I'm not really willing to spend the money on a surefire product.. ONLY if it's the best and this is a long term investment. But I'm looking for the brightest and cost effective solution.
