I have wasted some many LEDs because of this. I first blew up 24 Leds then i doubled the leds to 48 same thing happened. i've connected it with a 15R/10W resistor, it seems to be working pretty fine now. I just want to know my calculations like
* How long the battery will last?
sorry for the stress, I'm using a 15R/10W resistor.
from your reply 24*20mA=480
2*3.2=6.4
therefore total power should be 480*6.4=3072w ?
or is there something else i'm missing?
I'm running 48 leds with a 6v 4.5AH lead acid battery, there are 20 leds connected in parallel each parellel line has got 2 leds making them 48 leds. the leds are white leds. please i need to know the total current and watt of the leds and how long the battery would last. please check the...
