Got a reply from viparled eBay shop, may be of some interest to some of you:
"Hi,
Sorry for the confusion.
Pls do not worry,we are really vipar.Counterfeit someone else's trademark is illegal,
Edd (the main charge person of website viparled .co.uk)will kill me-

We would like to sell only the B series on website viparled .co.uk,because they are our featured product.
The B series come with high cost,every modul has a heat sink and come with 90 degree lenses.
So it is more expersive.
If there is any request,pls feel free to contact us.
Thank you and best regards.
