edit: it appears this bin has been around a while... i thought it was new since i havent heard of it in any lights

It is indeed a new offer. The U3 was specified in the documentations since some months, but it was not really available in the shops.

looking at the data on this copper mcpcb... it says "The back side is holohedral golden."

what the heck is "holohedral golden"?? Anything like "hella golden"? ;)

Is this just marketing talk for a thin gold layer?

Holohedral, "holo" meaning hollow in Italian, and hedral meaning church. The word holohedral means "hollowed from a church". In this case, it means that the gold was scavenged from a church, most likely by thieves or burglars.







I think it is marketing to say that the gold was crystallized onto the copper, and is at least one crystal thick.

I have no idea who translated this to english, but on the german site it just says it is gold plated. It is also not listed as a translation option in the sites I usually frequent, and very rare even in google search.
