Does any know of a recharable battery that can be used with a 5 Watt Luxeon 3 x 123a flashlight? I have the 5 Watt LED Torch light, and I would love to be able to use recharables which won't burn it out but I don't want a dim light. Most Litium Ion's are 3.6 v which I would think would be too much since I need three 123's to power this unit. Any info would be great.
