That is nice! Are those still made?

Preheat Fluorescents forever!
I love diesel engines, rural/farm life and vintage lighting!

Nope no longer made. I heard all power twist lamps have now been discontinued, unfortunately.

May all the great lighting technologies have their place in history.

Not so fast there. I just checked Duro-Test's website and the Power Twist is still being manufactured.

I heard this from another collector who called Duro-Test and he was told that Power-Twist lamps are no longer made.

They are right there on the home page of their website, even listed as a "top seller". I would LOVE to get some! I wonder if the new ones are mercury starved like so many new lamps?
