The fixture in an LED tube installation is permanent, but the LED tubes are not, thus they may be replaced by the building's user. Integrated LED lights offer certain undeniable advantages: you don't have to worry about the design of the fixture body, and they can be controlled using a variety of control methods. The major disadvantage of integrated lights is their cost. You cannot replace an integrated LED light as easily as a standard bulb, so care must be taken when removing individual lamps from the fixture.
