I have just installed my new 2700K LEDs and whilst they work fine with my glasses - no buzz etc as you can see here just the right one - warm white . I've installed two more in the foyer and the same thing - one looks like our 3000k and the other is warm white which is exactly what I was hoping for. I don't understand how that happens unless they were packaged incorrectly by the manufacturer Parmeda. Does anyone else have this problem?!
