I have very low ceilings but still need to use a short ladder. Want to go with those type of lights that have no bulbs to change out. Think they have some sort of strip bar inside the light fixture. My electrician mentioned just changing out to LED T8 light bulbs but I hate the look of the utility lights altogether plus some are older than the hills, some had to have their ballast changed out, some are 8ft but most of 4ft doubles.
