During a brownout do the CFLs work at all? The long 36/48 inch fluorescents barely come on and constantly flicker so they are worthless during brownout. The incandescents are fine in a brownout. They just give about 1/4 to 1/3 less light but they turn on and don't flicker and you can use them.
That must be one heck of a brownout.
I just swapped out our T12/magnetic florescent light with T8/electronic ballast. The GE ballasts I used are rated for a wide voltage range, 108-305V. Not really for brownouts but so one ballast can be used in multiple locations.
