Replacing Cree XP-E Royal Blue LEDs

[Jaws]

I have a few burnt out Cree XP-E Royal Blue LEDs that have burnt out and I need to replace them. It looks like the XP-E's have been replaced with XT-E Royal Blues which are 20% brighter. Should I be concerned about the difference in brightness if most of my LEDs are XP-E's? Thanks in advance.
