What I have exsisting is a 4 lamp 4 foot fixture with two magnetic ballasts. As it is now, they are switched, 2 lamps per switch. I'm converting it over to a electronic ballasts. Can I use a single electronic to run all four lamps as opposed to running two ballasts switched? Or is there a code that I have to keep them switched? Thanks in advance for any help offered. I'm in CA btw.

It's common here to install 1-4lite T8, F32 ballast to replace 2-2lamp T12 F40 (F34) ballasts.
CA may have an energy code, requiring "split wired" fixtures.
It's best to check with the local AHJ, or utility Co.

All - CA does have their Title 24 - Energy Conservation code requirements - (this is a large body of law covering lots of areas - I don't have the particular legal citation but any bldg. dept. will have that information for you ) this 'split' switch is a requirement.

Contact me via e-mail and I can give you some links for Title 24.

Basically you will need to retain "Bi-Level" switching, which cuts 1/2 the lighting power [half of the total lights per room or area].
This can be done by either using 2 lamp ballasts in each fixture, or creating a "Checkerboard" making every other fixture on the opposite switch. Checkerboard method allows you to use 4 lamp ballasts, but does not end up as uniform as the "A/B Per Fixture" method does.
