October 10 is the anniversary of the installation of our biggest lens!
In 1901, workmen spent a great deal of time installing a brand new 1st order Fresnel lens made by Barbier, Benard, & Turenne, which was actually larger than the earlier first order Fresnel lens that was previously in the tower and had been damaged beyond repair in the 1898 storm.
The new lens had 192,000 candlepower, and it was lighted for the first time on the evening of October 10, 1901. In 1932, when a new electric light was installed to light the Fresnel lens, its candlepower was increased to 4 million, reportedly at that time, making it the most powerful light on the New England coast.
The Fresnel was replaced in 1946 by a Crouse-Hinds, double-drum, rotating DCB-36 aero beacon.
