Trying to replace this light (The American Sanitary MFG Co)

[denogginizer]

Has anyone seen this light before or know of a direct replacement?
It's a little more than 10 inches across.
It has one screw at the top and a tab at the bottom to hold it in place.

Writing on the housing:
The American Sanitary MFG Co
Cat. No. 41291
USF With Housings No. 41173

I would like to replace it with an LED fixture.

Even info on something that would fit in the hole (with the one screw and tab) would be helpful

Thanks!

Universal Light Ring Adapters Parts - INYOPools.com, this is another brand

This appears to be a second thread with same obsolete housing.

Can you report if any of the conversion rings were successful? Or did you have to break ground and replace nitche?

Appears I have a similar situation. In my case stamp on housing reads:
Sta-Rite Industries Inc
American Sanitary Div
CAT 41290
Use with housing CAT 41173
300W MAX 12v Par 56

From what I can gather, American Sanitary is a participation corporation (designers and engineers can bring their product to market with participation agreement with American Sanitary). In 2004, Pentair acquired Sta-Rite (copyrights, trademarks, patents, etc), and are unable to reference parts prior to their oldest Sta-Rite 1999 parts manuals). Pentair continues to use Sta-Rite name, but pool owner must break ground and replace conduit, housing, fixture and lamp to current models.

Today, the Pentair representative did say if pool lights are from Swim Quip or Sunlite series, they are obsolete (no serviceable parts). Pool was constructed in early 70's, so series could be from 50s or 60s.
