I have sucessfully specified 2700K fluorescent lamps and CFL’s for clients that required an “incandescent look”, mostly in nursing homes here in the States. Interestingly enough you can also specify 2700K for LED cove lighting applications!
You can now get “instant on” CFL lamps that require no warm up. Phillips Amalgram (SP?) is one brand that comes to mind. My wife just bought some for our bathroom and they work great.
