How does this compare to an Innova X1? Is it a lot brighter? I never use my X1 cuz it's not bright enough.
I can only comment on the X1 generation 2, which is a flood, not like the other generations that I believe are like a follow spot.
They are two completely different patterns. The MS is much brighter with a surprising amount of throw (compared to the X1). It has a very nice beam with a nice hot spot and good surrounding flood. The more noticeable difference is the surprisingly nice white tint of the MS.
The brightness is, of course, at the expense of run time, but why are you even asking to compare an AA light with an AAA? The X1 is a great 'go to the bathroom' light or read in the dark. It's appeal is that it's built like a tank (like the X5) and is long running, but it's heavy and bulky for an AA light. It's a scaled down X5 in size and brightness, but the more common AA format.
BTW, I'm looking at doing a 'group buy' on the Microstream and Nano.
