Default Is it safe to underpower a driver and diode?

Simple fast question,
Is it safe to underdrive a driver and diode assembly? I ask because i just finished my NEBO CSI TACTICAL laser host up and it needs at least 6v to operate at the level i require "450Ma" BUT i dont have my high voltage ultrafire aaa's yet...its gunna be about a week or so before i get em...so i stuck in 3 1.5v "not1.2v" aaa's and it will still laze when i turn the pot all the way up. i feel kinda anxious about using it because i dont want to hurt it....but at the same time i cant stop playing with it!!! so will it hurt it?

thx
~Dark

You won't hurt the diode or driver by using an input voltage that is too low..
You didn't say but it seems you are using a DDL type Current regulator driver..
If the input voltage is too low the drive will not regulate up to the required current.

When you get the proper input voltage re-established... don't forget to turn down
your pot first.... you just stated that it is at MAXIMUM
