Here are several cases of 48 inch Power Groove bulbs.
These are not easy to find as they have been out of production for many years.
I bought a case of these from this seller before and they all worked when tested.
The packing was well done, so there were no broken bulbs.
I made a fixture for them from a 8 foot fixture.
The modified fixture is shown on my gallery page.
I have the fixture connected to my garage door opener light and it has been working flawless since the first of the year.

Seems like more people are going through their storage and pulling out some old bulbs and listing them on ebay.

Day light bulbs.
I have never seen this brand of bulbs before.

Here again a brand I have not seen in a VHO.
