Depending on the LEDs you use it's fairly easy... If you are using crees then you would need a heatsink as they heat up abit, you can also order cheaper 1w led from china and use buck pucks to power them, not dimmable but decent.
Are you planning on supplementing the flourecents or completely ripping them out and retrofitting with led?
