Noma introduced this style of bubble light in 1948. Soon thereafter, they were discontinued as they warped badly from the heat of the bulb due to their shape. The space inside of the saucer body was too small and they overheated. In 1949 Noma went back to their original design. For that reason this style is much harder to find than the other Noma bubble lights.

Also included are parts of 6 other bubble lights. The long clear one is marked "GE" on the bottom.

I tested each of these bubble lights with a continuity tester and determined that each one is working (a continuous circuit exists).
