More Modern Junk

Went to Home Depot Sunday after church to pick up 4 ft shop light to replace the burned out one over my workbench.  Entire light was cheaper then just buying a ballast, (another gripe for later).  Got the new light home hung it up plugged it in and voila, one light wouldn't come on.  Jiggle new bulb light bussed and light half way.  Get another bulb, put in same results.  Made in Mexico, I guess I should expect only one light to come on.
