Black Diamond Astro vs Coast HL7
Black Diamond Astro 175
The reviewers at OutdoorGearLab have featured the Black Diamond Astro 175 in their The Hunt for the Best Headlamps roundup. However, it fell short of making it to the top of their list.
Taking a look at the Coast HL7, it got featured in roundups from two reliable sources that conduct their own testing - OutdoorGearLab and Switchback Travel - but it fell short of earning a top spot in either.
We conducted an analysis of all of the review data that we could find on these two products. First, we focused on sources that tested and rated both of them, like OutdoorGearLab, and learned that they all showed a preference for the Coast HL7.
Then we took a look at the highest review scores that these two Headlamps received. We found that the Black Diamond Astro 175 managed to earn a rating of 9 from OutdoorGearLab, whereas the Coast HL7 got its highest, 10, score from reviewers at OutdoorGearLab.
Lastly, we averaged out all of their review ratings and observed that the Black Diamond Astro 175, with its 9.0 average, performed considerably better than most Headlamps - the mean score for the product category being 6.0 out of 10 - while the Coast HL7 managed an average of 10.0.
There's one caveat here - it might not be entirely justifiable to do a direct Black Diamond Astro 175 vs. Coast HL7 review average comparison since they aren't priced the same and more expensive products tend to get higher review scores from some sources.
