I order the little 4.5 ft. tree. The website description, which I studied before purchase, said this small tree had 550 lights on it.  I got the tree and it had 50 lights on it, if that.  Wayfair wants to charge me $13 to return it even though I bought it based on this untrue advertising on their site. TODAY I looked at the specifications for the 12 ft. tree and that one also says it has 550 lights. 

Whoever wrote the tree Specifications said each tree of every size has 550 lights on it. Now you know. the true light count is an unknown.
