These are low-energy fittings, aren't they - aren't these compulsory in new builds now? Could be wrong...
Whatever - all rental properties these days have to have a valid Energy Performance Certificate (presumably you were shown it before signing up, as is the law?) and one criterion is the provision of energy-efficient lighting. Just providing CFL lamps in standard fittings doesn't cut the mustard; you have to have fittings capable only of accepting energy-efficient lamps.
It's all bollocks of course, which you as a tenant are proving neatly with your desire to rip out the 'energy-efficient' lighting and replacing it with incandescent bulbs - howewever I'm just providing the background and explaining why you shouldn't shoot the landlord.
That said, it's not reasonable to find half the lights not working on moving in, and if I were you I'd be insisting that gets rectified. FYI it's most common for the tenancy agreement/inventory to state that at the end of the tenancy all lightbulbs must be in working order, and will be chargeable if not - dunno what yours says. Have you completed/signed an inventory?
