The fixture being a LED type and being dimmable, the only thing having the right voltage is that the transformer failed. If you have it on a dimmer, that might be what failed the ballast over time. Anelectronic dimmer is required. The cost of a replacement transformer will be almost as much as a new fixture. The fixture is the problem.

It was a fluorescent t8 not dimmable
Expert:  Mike G. replied 7 months ago.
The make and model number given was for an LED fixture. No matter, the voltage is correct and it won't light. If the lamp is slightly dimmed on the ends the lamp may be failed, if not the ballast has failed. Unfortunately many electrical products made in China, fail prematurely due to poor quality control or cheap components. Replace the fixture.
