Candler that you hold over tray of eggs?

[Mrs. Mucket]

I was sure I had seen one, but can't find it by googling. Instead of holding the egg to the candler, you hold the light over the eggs. It was supposed to make quick work of a large tray of eggs. But I was wondering how you could see much without holding the egg up. Anyway, does anyone know what I'm talking about?

I have never heard of a candler over the eggs but have seen them under the eggs.

This is what I use.

This is a video of an egg at day 10. Click on the image.
