I bought 2 CMG Infinity Ultras around 2 months ago. I have been carrying one around as an EDC while keeping the other one aside as a standby. Initially, I didn't notice any difference between the colors of the two, but after 2 months, I noticed that the color of my EDC is noticeably lighter than the one which I chucked aside. The color is still very even, and none of the lights received any abuse at all. It looks like the color just sort of faded away. Unlikely to be caused by the sun as I always EDC the light in my pocket. I didn't notice the difference until I put them side by side again. Kinda funny isn't it? /ubbthreads/images/graemlins/grin.gif
