So I found a great deal on a new Cygolite Miticross 350. But it looks like the item is from 2009. Will this affect the battery, brightness, etc? I bought a 2yr old Cygolite Hi-Flux used and it doesn't seem as bright as it's 150 lumen output, more like 100 even without the wide-angle lens. For $150 is it a good buy or should I just suck it up and pay full price? Again, the light is being sold on Amazon as new but the date is 2009.
