This adapter must be a newer model than the one I have, mine appears to be made by Thorn before GE bought the lamp division off them. Mine also has a heavy magnetic ballast inside but has an electronic starter so it starts almost instantly.
I've read about electronic ballast versions but never seen one in action until now, cool adapter!
Edit: The video if it can be seen here:
