I have 2 Fenix L2D lights, AA. The 2 year old one is no longer bright. It still can go into super flash mode but not as intense of a light, virtually worthless on high. The 1 year old light continues to shine brightly. I have switched batteries with no improvement. Is the life expectancy for this light 2 years?? Is there something I can do to improve the brightness. I gotta think it is out of warranty. If so time to buy a new light.
FWIW: I use lights almost everyday during the winter so they do get a lot of use.
