The current limiting resistor is required in most cases. However I'm guessing that in this case will be fine because of such low voltage and the corresponding low current. http://led.linear1.org/why-do-i-need-a-resistor-with-an-led/1/ http://linear1.org/i/led-curve.gif Let me conduct an experiment with 2 LEDs on a 2 AA battery pack and get back to everyone about how long they operate.

This is required even on a 3v system if you want the best results.

I like the extra AAA boost, looks like yours had to be a bit more involved. Cool nice work, same wavelength man! I like the extra AAA boost, looks like yours had to be a bit more involved.

You're right. mine looks pretty different from yours. It also uses 2 AA bateries, so I think there won't be a problem. :-) Really great webpage by the way. I will show you the result, this week.

Good luck, you have a completelly different light system, but it could work. Cool, thanks for the pic. Good luck, you have a completelly different light system, but it could work.

I put a pic online of it: http://skitch.com/ronski/7hpa/dsc01378.jpg later! Ronski thanks a lot,

That is actually a very good voltage for LEDs to use and no resistor is required. If it was 6 Volts than yes, you are correct, we would need to calculate for a resistor value. Good Question.
