One end of a F15W/29-530

This is one end of a F15W/29-530 florescent lamp, not sure which end in space but I know it's at the end in time - it's at the end of it's life and need replacing.

Not sure if I should replace all the units with LEDs or just buy another tube. LEDs take less electricity and run cooler but require me to do more than just replace a tube...
