Many thanks, Cathy. These really are stunning photos! The centre one is particualr really catches the reflection and refraction superbly. Pat on the back for Hubby!
Incidentally, I read somewhere that the power of the bulb used in most lighthouses is a mere 300 watts or so! The whole thing relies on the lenses to create such high power, and it means the bulbs have incredible longevity.
Can anyone confirm this?
