.lighting is about average for the internet. Across 5,372 graded .lighting domains, 81.2% score an F — roughly in line with the 78.3% global average. 2.3% earn a B or better. Most .lighting domains can still be impersonated in email, but the ending shifts the odds, not your own domain's grade. As of 2026-08-16.
How do .lighting domains score?
Aggregate grade distribution across all graded .lighting domains — we never publish an individual business's grade. As of 2026-08-16.

|---|---|---|
| A+ | 2 | 0% |
| A | 10 | 0.2% |
| B | 111 | 2.1% |

Does .lighting make a domain secure?
No — and that's the most important thing to know. A domain's grade is decided by how it is configured (SPF, DMARC, HTTPS, DNS), not by its ending. Choosing .lighting doesn't protect you, and a high-F-share ending doesn't doom you: a correctly configured .lighting domain earns an A while the crowd around it sits at F.

Frequently asked questions
Is .lighting safe?
On average, .lighting is about average for the internet: 81.2% of its 5,372 graded domains score an F as of 2026-08-16, against a 78.3% global average. Most domains on every ending are exposed — the ending shifts the odds, not your own domain's grade.
How secure are .lighting domains?
18.8% of .lighting domains score above an F and 2.3% earn a B or better. The rest fail the basic externally observable protections, most importantly enforced SPF and DMARC, so they can be impersonated in email.
Does choosing .lighting make my domain secure?
No. A domain's grade comes from how it is configured — SPF, DMARC, HTTPS, DNS — not from its ending. A well-configured domain earns an A on any ending; an unconfigured one sits at F on .lighting too.
What does "grade F" mean for a .lighting domain?
It fails the basic protections we can observe from outside — above all, it has no enforced SPF and DMARC, so its email can be forged and its customers targeted with convincing fakes.
