These are the weld points (genuine bulb on the left):
The image was taken from here, which gives a few more things to look for:

It seems to vary from one fake to another which of the traits are present. The fakes I had were almost identical to the originals (as far as I could tell) apart from the missing weld marks and the missing 'curved' part mentioned here:

The seller I bought from also sold on Ebay (and had lots of positive feedback) but I bought them from their website instead.
The name of the seller's business you bought from doesn't happen to contain the word 'style' does it?
