In actuality these are all registered trademarks of Scarlet Tanager LLC which is their parent organization/owner. Over the years each has been bought out by ST LLC.

It does not mean that they are DBA as each other. It means it is Scarlet Tanager LLC DBA as Henry Fields, Michigan Bulb Company, Spring Hill, etc.

The BBB links all subsidiaries to their parent corporation but they are still independent companies operating on their own but under the auspices/control of the parent company.
