HHaase, I purchased a pack of 100 LEDs and they are super bright red. Yes 3V was a bit surprising for me too. And the amperage was rated 0.03A.
The OP is talking about red 3 volt LEDs;A blue or white LED is from 3V to 4V. Then 3V is the minimum voltage. Some stores pick any number for their ad. Many pick the number 3.

Do you have a spec sheet or a part number for the LEDs?HHaase, I purchased a pack of 100 LEDs and they are super bright red. Yes 3V was a bit surprising for me too. And the amperage was rated 0.03A.
I'm not trying to hijack this thread but I'm working on sorta the same thing. White LEDs to convert my running lights on a boat. Interesting thread.
Most common LEDs have steel leads that will rust.In all honesty, I'd probably try and track down a pre-made marine grade unit for that application. The electrical side of engineering that type of layout is easy enough, but the corrosion issues are pretty significant out on the water. Particularly if you're on salt water.
Hey guys! A slightly different approach but it worked!
I took each one to be 2.9V instead of 3V. Now multiplying 2.9V by 4 gives 11.6V. Using the formula R = [ V(S)-V(L) ] / A
R = [ 12 - 11.6 ] / 0.03 = 13.3
