This is the same listing I asked about in this thread.
The emitters arrived to me in the US in 1 week! Each star was individually sealed in static shield pouch. All in good condition. Don't know the color bin but the tint looks similar to my P60 Xenon.
I'm using them for some low output house lights.
This is my first time seeing Cree X-lamp emitters, warm white no less, mounted on stars for less than $2 per. I guess that'll be a more common occurrence once XB-D and XT-E emitters become more widely available. That might explain the price of these.
You need a well regulated 12v output or you can easily go over 6V limit of the drivers. They work best under 4Vs. But, maybe 3 or 4 of them in series can be used without problem.
