This is all a bit over my head. In super-layman's terms, I'm just trying to figure out how feasible it would be to power these LEDs off of batteries, in terms of determining how large a battery I'd need to power them for a given period of time.
To add to confusion, I just found a seller claiming to have 500cm of 5050's that run off of only 3x AA's (so 4.5V): **broken link removed**
I messaged them and they said they've tested it as running for a full 4-5hrs off of just 3 batteries. When I hooked my strip up to 4.5V, it was only able to illuminate Red, and barely at all...
