Streamlight 2 D...does it have a step-up? If it doesn`t it will be the saddest ten led light out there...and the L-1...the single 123 batt light their coming out with too...better have a step-up. I can only assume it/they do. Would that mean it has at least some degree of regulation as well? Like the aaa Arc? Anyway I ordred one from Brightguy...suppose to be getting them in around the begining of next month. I`m not sure how well the straplled reflector will work with ten led`s taking up some of the reflector space. And it will be interesting to see how well the focusing works. I wonder if the center bulb is running off 3 volts or if it runs through a step up as well...if not I would not think it would be that bright...about the same as the old Surefire single 123 batt driven lights (what were they called E-1`s?) For the price this sounds...at least on paper...like great bang for the buck. But if no step up...these will be a total joke.
