Was This Mid-Century Modern Bath Fixture Used In Many Eichlers?

We've owned our Garland Park J&E Model 71 Reverse Plan Eichler since 1971, so the house was 16-years-old when we moved in. It is now 48.
It came with light fixtures in the 2 bathrooms like the one in the attached image. As the photo shows, we have only one light socket wall fixture remaining but still have both of the glass enclosures.
Does anyone else recognize it? Were there many of Eichler's homes built using this style of fixture?
Now that LED bulbs that can survive in a closed fixture and even work with a dimmer switch are reasonably inexpensive, it should be possible to get a reasonable amount of light from this fixture without its becoming hot and wasting a significant amount of electricity.
Thanks,
