Fresnel Lens


The lighthouse's light is a third-order Fresnel lens. It's five-foot high and has 52 prisms. It was made in Paris, France and gives off 1.1 million candlepower. It's range is 20 miles out to sea. I took a lot of pictures of it while at the top of the lighthouse. It got very hot standing near it.

Hi from South Shields, nice picture you have here today. If you search lighthouse you will find a similar picture in my blog.

I need your support, see my latest post at South Shields Daily Photo

Photographers rights in the UK and worldwide are under increasing threat and we need to make a stand now!

Unless something changes dramatically, this will be the last ever post at South Shields Daily Photo.
