The white LED strings look very nice and I definitely agree that white incandescent strings have a very short market life left. But the colored LED strings which are sold at Home Depot and similar merchants in the USA have very different colors than the incandescent strings.

I personally find the colored LED strings to have very unpleasing colors compared to incandescents. I've tried a few different "brands" (in quotes as the brand is mostly meaningless afaict) of LED strings and all were not to my liking.
