How long will the ballast of 12v 1A last in led strip?

Hello, first of all, explain: ballast can't be connected to LED light bar. Is the ballast of 12V 1A the driving power supply? If yes, this can be matched with a 12V 12W light strip, which is more suitable. As for the length, it depends on the bulb and arrangement structure of the light bar. The most important thing is that the input voltage and power of the light bar should match. Yuhong Optoelectronic Co., Ltd. can help you answer more questions.
