Color will be you biggest problem finding LED lights that you like.
I like colors in the 5000 kelvin scale. Not yellow/warm like many put in.
Even if you find bulbs that fit into same location as florescent bulbs you will need to rewire your fixtures. There are replacement fixture that will also work.
I did all my fixtures with LED strips and voltage regulators.
On another forum there is a good thread on replacing florescent bulbs with LED.
Here is a link. Here is a picture of my LED project. 2 fixtures on right are in the 5000 color range. The rest are closer to 6000.
