beware, rechargableīs cr123īs are usually 3,7 Volt norminal, with a starting voltage of 4,2 Volt when itīs fresh of the charger. 2x 4,2 Volts in a 6 Volt light can have very dark results. There are also 3,0 Volt rechargableīs, but there are 3,7 Volt and instandly drops to 3 volts when under load, but normal cr123 are 3 volt with no load and less when it is underload. So a 3,0 volt rechargable cr123 will also overdrive most lights.
