It wouldn't hurt to see what the coach voltage is, but unfortunately with LED's you get what you pay for. That's one of the reasons all the LED's I have were bought in Quartzsite where I knew where the vendor was and could return them if needed. Color temp is another personal gripe and it took 10 years for them to get that right. Now you can't hardly tell the difference.
