I'm wondering...I'm using a red P4 LED for my saber, but I need to know what voltage battery would be best? Here's some more information (if it's helpful): I'm using a red P4 LED, 4AAA battery back, and it's a sinktube saber, so I don't want it to get too hot. Help? UPDATE: I realized this is a stupid question and realized the answer right after I posted, stupid me. Sorry, guys, I messed up.
