What innovations did John Smeaton introduce at Eddystone?

Smeaton 'announced it as his intention to build a structure of such solidity that the sea should give way to the lighthouse, and not the lighthouse to the sea'^[1]. He 'resolved to build it of stone'^[1], which was a change from previous structures. He moored 'a vessel within a quarter of a mile of it, which should accommodate the workmen and their tools', instead of making along voyage from Plymouth on each occasion^[1].

Smeaton decided 'to adopt Rudyerd's idea of a cone but to enlarge the diameter considerably, and, on the whole, to keep before him as a model the trunk of a stately oak tree'^[1].
