For replica lighthouse lenses, we can tell you most likely what the original optic configuration was of the Fresnel lens and can also provide a replica quote to you. Please contact us at Thanks, Jeff

Also try the Maritime Museum in Marquette-they have about 4 or 5 lenses there and could probably give you more info about the Fresnel Lenses. They have the original lense there from Stannard Rock Lighthouse! You could probably get some info too from the Coast Guard.

We are restoring the Grosse Ile North channel front Range Light. Structural restoration is complete. We need plans/specs for the original lens and light and any change with the opening of the Livingstone channel in 1912. We are considering a replica lens.
