on another flashlight forum someone asked a question, what led is it?
he bought c8 with led, that seller claims is xml2, however, it does not look exactly like xml2.
it has die that is like xml2, with tiny dimples not lines like xml, and has 2 bond wires just like xml2, not 3 like xml, however the base is green just like xml.
No, these are being sold in most, if not all, of the lights we bought back a few years ago. Any "XM-L T6" light that is being offered now has these fakes. I've had 3. A vendor having old stock might be the only exceptions.
