They were cheap but that's where the benefits end. You get what you pay for as while I can't believe none broke, the packaging was terrible all were defective. Many had black, hard glass formation on the bulb, all had uneven glazing, some were more opaque than others, most were streaked, and there were at least two places where the filament was bent or flattened and they would not go into the bulb screwed outlet in general. really rubbish, they're back, save your money.
