Review on Sunco Lighting Vintage Filament Decorative Industrial Electrical and Lighting Components by Grace Brown

The place where the bulb is screwed is of poor quality. We have lights where the original bulbs are failing so I bought these to replace. I tried 1 bulb first and it blew out after a couple of weeks. I tried another lightbulb and it blew the next day. I thought maybe I didn't turn it on properly. I tried unscrewing them a bit and they worked but flickered. I unscrewed them completely and compared them to the original bulbs. Below the threads is a rounded portion at the bottom that needs to touch the socket to properly complete the connection, which wasn't the case on these bulbs. I bought different lamps to compare. The new bulbs did their job and now I can't return these bulbs as their return period is very short. I think I'll see if I can use them for something else if they don't end up in the trash.
