The lampe gras blanche is a type of light fixture that is typically used to illuminate a dining table. It consists of a long tube with a bulb at the end and a metal reflector at the bottom.

The lampe gras blanche was first designed in France by Jean-Baptiste Louis Lampe in 1878. It was originally made out of glass and metal, but today it is mostly made out of plastic due to its durability and lower cost. The lampe gras blanche is also known as the "French lantern" or "glass lantern."
