Just averages, drain about 4 W. 4 AA NiMH = 5 V, 2000 mAh, will run for about 2.7 hours. 12 V, 100 Ah car battery = about 300 h. Required 228
= 228 h.
I had good luck with a stage hat that had 30 LEDs, 3 parallel strings of 10 LEDs in series with 3 resistors. 1/4 th of LEDs on at a time. Driven from 4 AAA, NIMH batteries & a boost converter.
28 gauge wire gives about 15 ft. / ohm.

Perfect, so about 3mm or 6mm. I usually see them measured like this.
I guess it depends on where you are. We use inches here:

If you're in the US, I can give you a good price on yellow 3/32" or black 1/4"...

I was looking on ebay, and they came from Hong Kong which is why I probably saw so many measured in mm. I am in the US.
