A few claims that are easy to over-smooth. Each one is set beside the source, not knocked down for sport.
If a good source once said Fastnet had a range of 28 nautical miles, that is still the range of the light today.
The official meaning of Minot’s Ledge is “I LOVE YOU.”
If the 1911 Britannica gives a height for Bell Rock, that is also this site’s figure for the light today.
Irish Lights records that the light was converted to electric on 10 May 1969, and then had a range of 28 nautical miles and a power of 2,500,000 candelas. Those are historic figures: the range published on the same page today is 18 nautical miles.1
