405nm or 447nm? Need advice!

I think im going to go with 405 first honestly.

Found a cheap pen that is located in San Diego, California(which is close to me)

Lets me first start by saying pardon my gullible ignorance! I retract everything I said about the Ultrafire batteries after reading this thread!

I do believe I will be buying quite a few new batteries now!
