These LED tubes were used to replace fluorescent tubes in fixtures controlled by a Lutron Caseta switch. After replacing the bulbs, it was impossible to turn off the light except with the switch. The support team for this product never responded to my request for help with an issue. When I replaced the Lutron switch with a Teckin wireless switch, they worked great. Color and brightness are excellent and well worth the extra effort to get them working. They were almost returned due to the lack of response from tech support.
