For $15, you could have a flashlight with superior quality, a great beam that is really bright, and long life! I am talking about the ProPoly modified, but only if you are up to modifying your lights. I recently modified my ProPoly 4AA with a Seoul P4 and the result is beautiful! It has the same beam pattern as the original ProPoly, but is 2 or 3 time brighter. In addition, you get the same great long runtimes!

If you try it, if you have questions, leave a post. I can help you through it if you would like.
I guess if you do not want to bother modifying your light, you can try other flashlights instead. I just wanted to promote modifying the great flashlight with a high-tech LED that will give you nice results. The ProPoly has a beautiful, deep reflector and the SSC P4 is bright and mates up with it well. Well, good luck!
