I bought these because they cost significantly less per bulb than the ones I bought at the local hardware store and they were identical. When I got them I needed to replace a burned out bulb so I tried new ones. To my surprise, unlike the bulbs I used, I couldn't fit new ones into the socket. When comparing it to the old bulbs, it was immediately noticeable that the old pins were pointed/beveled while the new ones were blunt. Old lightbulbs fit in sockets with no problem, but this one doesn't. It appears to be fake and a waste of money.
