I had the same situation with some LED lights from Amazon. I've had horrible problems with lights made in China before, so I specifically looked for LEDs made in another country. I found the ones I was looking for on Amazon, where it said that they were made in Malaysia. It was all just a big scam, and all that came in the mail were the same low-quality lights I've seen many times before. Luckily, I got some other lamps from this website
