[color:"green"] Matt:
My first thought is that the capacitor is not working properly. In theory, the brightness should stay constant but the time between flashes should increase as the battery level decreases. I have a generic "D" cell life vest strobe that functions in this manner. Is the unit actual surplus? If so it may have been determined to be defective and auctioned off. On the bright side, the guy selling these units appears to know his stuff based on the other products he sells.. I would drop him a note and see what he says. [color:"green"] [/color]
