Coast HL7 vs Black Diamond Astro

Analysis:

The Coast HL7 and Black Diamond Astro 175 make for good, if unremarkable, Headlamps at their respective budgets.

With that said, while they both should serve reasonably well, you might want to look into other options at the $45 and $16 price points - it's likely that there are some better alternatives available.

If you want to learn more about the Coast HL7 and the Black Diamond Astro 175, however, we prepared a summary of the information that we have:

The Coast HL7 managed to earn a spot in roundups from two sources that are known for their trustworthy review methodology - OutdoorGearLab and Switchback Travel - but fell short of making it to the top of their lists.

As for the Black Diamond Astro 175 - OutdoorGearLab, a source that conducts reliable hands-on testing, has featured it in its The Hunt for the Best Headlamps roundup. However, it didn't make it to any of the top spots.

When we thoroughly analyzed their review scores, we learned that all of the sources that tested both Headlamps, including OutdoorGearLab, preferred the Coast HL7 over the Black Diamond Astro 175.

We also took a look at which sources they managed to impress the most. The Coast HL7 was liked best by OutdoorGearLab, which gave it a score of 10, while the Black Diamond Astro 175 got its highest, 9, score from OutdoorGearLab.

Lastly, in order to better compare them to the rest of their competition, we averaged out their review scores. The Black Diamond Astro 175 managed to get 9.0 out of 10 - considerably better than the 6.0 review average of Headlamps in general - whereas the Coast HL7 earned 10.0 points.

It should be said that doing a direct Coast HL7 vs. Black Diamond Astro 175 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.
