Thanks TJZ (Tom) for your detailed response. I have another question if you don’t mind. I understand the advantages of the 3V rechargeables is that you can get the different light levels. Are there any advantages of the 3.7V rechargeables over the 3V rechargeables, in terms of runtime or brightness? If not, why doesn’t everyone just buy the 3V rechargeables and forget the 3.7V rechargeables? I must be missing something here.
