Believe it or not, a guy just listed them as fuel cells with no description but good pics on the auction site for 59 bucks buy it now! I thought they were ACUs and checked the serial number fast and bought them! Thought I wouldn't like the warm gray but actually do...really makes reds pop.
Thats nice when you have a little luck. I havent used the warm grey lenses so much but i think they are ok.
