1,643,760,000,000,000,000 candela

In candlepower the sun's intrinsic brightness, as seen at sea-level, is equal to the light of 1,643,760,000,000,000,000 candles.

I could not find how many candela St Peter Port lighthouse is but the Hanois lighthouse is 89,900 Candela.

I did do a monomonday blip.
It's here.
