I'm often asked several times a month why light bulbs seem to burn out so quickly. It seems that some seem to burn forever and others won't last a week. So what's the deal? Is it just a bad batch of bulbs or could it be something else?
Over the years I've found a pattern to bulb failure, There seems to be a few variables that contribute to failure and there is a manufacturer, that I have noticed, whose bulbs seem to have more trouble than others. In fact, I generally ask if it is that brand of bulb that they are having trouble with and the answer is usually the same, "yes".
