Yesterday, 7 March 2016, I encountered this very large light bulb washed up on the beach.
Here's a picture with my foot for scale:
I don't know anything about vintage (?) light bulbs, so if anyone can provide more information about this bulb, I'd be very interested. Can you tell how old it is? What was this type of bulb used for? Are they still in use today?
You might have noticed that one side of the bulb (the side that was floating downward below the ocean surface) supported a few different pelagic animals.
Here's a closer view of that side:
And I zoomed in even in more so that you can see the pelagic gooseneck barnacles (Lepas sp.) and the bryozoans (off-white, rough patches):
I'd love to hear any ideas you might have about the type of bulb this is.
