All  Malaysian and China T5 led tube came integrated with base and small clip to install on ceiling or wall. Mr DIY stuff are not bad and easily available.

The all in one T5  (tube & integrated base) need to be discarded when the led or tube is spoilt.

To clarify on misconception that T5 is shorter than T8, thats not true. The "T" designation is only referring to diameter of the tube.
T8 is 1 inch diameter (standard tube)
T5 is 5/8 inch diameter (slimmer tube)

The normal lenght for Malaysian household used tube is 4 feet and the short one is 2 feet. Both 2 and 4 feet tubes are available in T5 and T8.
