m confused how cum 80 leds would work ok 6v battry for so long as shown in STADIUM LIGHT by dipankar ghosh.?

Every LED is connected to the six volts individually. That is to say that they are all in parallel and so each one would draw the same amount of current as if it was the only one connected to the battery. The resistors limit the current through each LED. Take whatever current that is and multiply it by 80. The battery is quite a large capacity one which explains why it can last so long. So take the ampere-hours capacity of the battery and divide it by 80 times the current flowing through one LED and you get the number of hours (roughly) that the battery will last. By the way, come isn't spelt cum and I'm has an I in it.
