Time to replace a bulb?
Black ends don’t require immediate replacement. But you should have new bulbs on hand so you can replace them promptly when they do burn out.Photo: Courtesy of The Family Handyman
Bulbs with black ends can run for a long time and they won’t damage your ballast at all. But you should have replacement bulbs on hand for the day when they begin flickering, take a long time to fire up or finally give up completely. That’s because running a fluorescent fixture with a burned-out bulb will damage the ballast.
