Difference between RovyVon Aurora A5x and A7x?

After looking around for a new keychain light for a while I’m pretty set on one of the RovyVon Aurora series. But can someone tell me what the heck the difference between the A5x and the A7x is?

A5 has a High CRI Nichia option, so thats better, to me, than

A7 has NO High CRI option
