Well, yeah I'm not 100% sure what the current is through those regular ones, but it's definitely lower than the super ultra bright annoyingly stubborn current draining blue LED
.
I mean, the battery life is fine if the circuit only consists of the 2 red LED's, but with the blue one, I'm testing that right now. I'm at work, and I'll turn the circuit on and see how long it lasts, then I'll do the same but just with the Red one's themselves, and I'll let you guys know
