So, I have a family event soon and I need to build a lot of small paper lamps that will light a tree.
My idea was to use a AAA battery, a 75 ohms resistor and a 8mm led. So according to the wiki specification of AAA batteries, in the worst case I could have 120mAh.
120mAh of charge discharging at 20mA = 6 hours of life ?
That will be the worst case, given that the quality varies from 120mAh to 1200mAh, using 660mAh I will get 33 hours of light, right ?
Please let me know if you see an error or if you have another idea.
Thanks
