The Eco-Saver FAQ (four page PDF) says that the Eco-Saver effectively deactivates the T8 fitting's magnetic ballast, which when running a 36W fluoro tube, normally draws and additional 11W, up to 12W. It claims that the Eco-Saver 22W product installed in an old T8 fitting puts out the same lumens as a T8 36W tube drawing 47W in that same fitting.
