Review on 💡 High-Quality 10-Pack MR11 12V FTD Halogen Spotlight Bulbs – GU4 Bi-Pin Base, Dimmable Warm White 2700K Light Bulbs with Glass Cover by Kim Aguilar

I give the 3 stars for fit and workmanship. "Don't expect to get bulbs that look so perfect on the stock photos the seller is showing." As I haven't tested the durability of these bulbs yet. The two metal studs/pins at the end of each bulb are at a random height and aren't straight either. This may be due to the small white packaging boxes they use because the onions are very tight in there and the onions have not had time to harden/cure. Or are they only made in China? transparent lens covers on it. All bulbs have integrity, which I checked with a multimeter. Although some didn't at first, I then noticed that the pins were lightly coated with PVA glue, which is used to hold the halogen bulb in place. So if yours don't light up when plugged in, you might need to scrape the stuff off.
