I've been using your website for sometime, and it's been quite helpful. However, I can't seem to find a clear-cut answer the following question on the site:
After reading reviews on here, I recently purchased a Fenix LD20 205 lumen flashlight (which I could not be more happy with), and I would like to know if there is a discernible difference in brightness between using alkaline and eneloops? Clearly there is a difference in runtime, but beyond that I'm not certain.
How do these batteries hold up downrange vs. traditional alkalines? My unit will be deploying within the year, so reliability will be just as important as performance.
