I'm a total newbie and am lovin' this forum! I'm in the market for for a small really bright flashlight. Was looking at the tk35 but it uses 18650 and CR123. Never used these types of batteries before and a little hesitant so I'm looking for something using AA's. What the brightest out there for less than $200. I would prefer something less than 8 inches in length as I plan to mount it on my bike. Thanks!
