    Thinking about buying a used flash (speedlite variety not studio flash) and was wondering if flashbulbs retain their power and color temperature over their lifetime or if this is something i need to consider.

    I doubt you need to worry about it. Amateur units haven't seen enough use over their lifetime to shift color. I doubt if most pro units have either.
    Re: color, the plastic lens might shift color.
    Power wise, more likely to have some power loss from the characteristics of the Main capacitor to age/degrade. Most likely from lack of use.

    Some cheaper older flashes (where they're using voltage control for power control instead of having a thyristor to cut off the exposure - we're talking several decades old here) have colour temp variations with power, but it's not something that gets worse with age.
