hi
so i bought this 3v LED and i'm going to power it with small watch 3v battery.
the first thought was to connect to 3V batteries (to get 6V) and then connect a 150 Resistor (6v-3v devided by 20/1000) to that and then to the LED
the miliamper for my battery (maxwell cr2032) is: Nominal Capacity (mAh)* 220
my question is how much time will that battery in average. hold that LED before it will have to be replaced ?
if we take the average 3v led lifespan.
(how do we even calculate that ?)
and if i will use 2 batteries and a resistor, will that double the lifespend of the led before the battery will have to be replaced ?
