i have a set of T8 lights i'm using to get my plants some light for the winter, but i had a bad experience with it. is there a fuse in plug in ballasts? i had a bulb that was not fully seated and as soon as i touched the lamp to power it off the lights went poof, nothing came back on. i'm gonna take a multi meter to the leads and see if i can get anything out of it to make sure i'm not loosing my mind. its just a typical T8.
