Black Diamond Astro vs Coast HL7
Black Diamond Astro 175
The Black Diamond Astro 175 makes for a good, if unremarkable, Headlamp for people with a $19 budget.
The Coast HL7, however, is merely mediocre at its $30 asking price, when compared to similarly priced products, and won't satisfy the needs of most people.
In either case, we suggest that you first take a look at some other options at the $19 and $40 price points before committing to one of these - it's likely that you'll be able to find some better alternatives.
If you're still interested in learning more about the Black Diamond Astro 175 and Coast HL7, however, we wrote a summary of what we could find about them:
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 5.6 from OutdoorGearLab, whereas the Coast HL7 got its highest, 6.8, score from reviewers at OutdoorGearLab.
Lastly, in order to better compare them to the rest of their competition, we averaged out their review scores. The Coast HL7 managed to get 6.8 out of 10 - considerably better than the 6.0 review average of Headlamps in general - whereas the Black Diamond Astro 175 earned 5.6 points.
It should be said that doing a direct Black Diamond Astro 175 vs. Coast HL7 comparison might not be entirely fair due to the difference in their prices - some sources don't put much weight on value for money and thus tend to give better review scores to more expensive products.
