I have a 4aa Q40 xenon Underwater Kinetics dive light with front switch. I would like to know if the 1.7v lithium AA cells are safe for the lamp in my flashlight. I dont want to blow a bulb because of the increase in voltage. By my calculations the increase in voltage would be 0.8v, that's almost a whole volt when you consider 4 cells over standard 1.5v alkalines. I would want to use these cells for an increase in runtime, and for longterm storage without leakage like akalines. It's a given that the brightness would be a little more intense because of the increase in voltage. Any input is appreciated. :thinking:
