Hello, I’m new to this forum. I’m trying to learn about 5v LEDs. Specifically, I’m trying to learn about the feasibility of powering a 5-6 meter string of 5v white LEDs with four AA batteries. My understanding is that 5v lights are more efficient compared to 12v, but the voltage drop is greater, making 5v a less than ideal choice for long strings. Is powering a 5v string of this length even possible with batteries? How much run time could I get out of them? In my testing, I’ve noticed that running LEDs continuously from batteries eventually causes them to get dim, but then turning them off and letting them ‘rest’ a bit makes them brighter again. Can someone explain that? In my application the LEDs will be on only briefly with long periods of inactivity between. I’m hoping that works in my favor... Any assistance would be very much appreciated. Thank you!
