i buy tons of these. for the price, they are awesome.
I suggest redoing some soldering (crooked emitters)and adding thermalpaste.
BTW theyre are ones that use "US made" batwings, but...they dont say lumileds on them (I have one). I looks to be a clone still tho. I have to remove the batwing and see if they have the bin codes or are just blank.
you get what you pay for. still a great deal.
