Why are cheap two-pack headlamps rated so highly?

Budget two-packs like the LHKNL and Blukar units carry enormous Amazon review counts and solid 4.5-star averages, which signals broad satisfaction for casual use. But Amazon averages are gameable and there's no independent lab data in our signals to corroborate brightness or waterproofing claims, so we'd set expectations around durability and real-world lumen output accordingly. They're excellent value for light-duty tasks, less proven for demanding outdoor abuse.
