From what I can tell, these lights are high quality. Unfortunately they will not work for my purpose, so I feel like I wasted money. I wanted warm white lights for a couple of small indoor tabletop trees. They are extremely bright and look more like cool white than warm white. I would not recommend these for an indoor tree unless you are using a dimmer. And I would suggest going with the extra warm white color if you want it to look more like incandescents. Also, the bulbs were larger than I expected. I thought the size would be equivalent to incandescent mini lights, but they are not. Overall these are nice lights, but I would personally recommend them for outdoor use only. I do appreciate that this company offers ROHS compliant Christmas lights, as these are difficult to find in the US.
