How to set a long lasting single LED unit?
Hey guys! I need help to extend the battery life to power a single 5mm red LED that will be left on 24/7. My set up is very simple. Just a battery holder with 2 AAA and the LED attached to the terminals. It is supposed to be visible inside the ceiling fixture for Feng Shui purposes (don't ask, I just follow). So far it hasn't lasted for more than three days tops. Its supposed to be able to fit in a tight space just enough to fit the battery holder. I need to make 3 of these for 3 locations so I don't think rechargeable batteries can be practical. Can you guys give me advise on this? I hope you guys can help. Thanks in advance!
