Put on the new light bulb, why the lamp still not bright
For the electronic ballast, if no response after the power supply the tubes, should first check whether the fuse of the ballast burned, if it is a filament is red, estimation is ballast resonant capacitance breakdown.
If there is a problem in the ballast itself, if the lamp filament of the inductor is red but can not be activated, most of the regenerator short-circuit damage.
Does your fluorescent lamp use a inductive ballast or an electronic ballast? Is the newly installed lamp tube not bright or filament red but unable to start? If the inductor is completely unlit, check to see if it is installed
