You are not overboard at all. Light geeks aren't impressed. Some of us own single system that has more than double the output you have on your entire bar, those are blinding at 50 feet. It isn't really bright unless you are cranking out at least 900 lumens (you have no more than 300).

Here's what a 900+ lumen setup look like.

The red bucket is at 20 metres (65 feet).
The yellow bucket is at 50 metres (164 feet).
The hi-vis jacket is at 100 metres (328 feet).
