It’s worth noting the fact that Streamlight has measured it’s intensity and throw distance for the two outputs. Companies generally only list a flashlight’s max output and sometimes those are not at all accurate.

It’s significant in that buyers can feel confident in the actual specs they provide; we appreciate it as well.
