Have to say the reviews have peaked my interest. I've got a rather shitty Engergizer hardcase (2xAA) LED flashlight (see http://www.energizer.com/products/flashlights/worklights/Pages/hard-case-flashlights.aspx). It's throw is rather pathetic and I'm not happy with it so it might be time for an upgrade. To give me an idea of what to expect can anyone give me an idea of how much lux the energizer has so I have something to use as a reference.. Also which battery type is the best? I noticed CRA123 etc in the reviews and since I don't have anything other than a AA/AAA charger I kind of would like the know what the best battery tech is to produce max lux vs operating time vs ability to hold charge since I'm not really vested in any. I really don't want something like my energizer lithiums (AA) which due to their leakage current will only hold a charge for a max week before battery starts to lose power. I think AA will be out of the question due to the short time and lower lux figures generally. TIA!
