I don't know.
I just bought a normal glass lens on eBay but I have received was this.
so I complain the seller. then he said he gave a fully threaded one.
but this lens come again.
EDIT : If you want to see[LINK]
I have soldered Micro Flexdriver for set the ampere to 500mA-1.5A.
and wires were also soldered.
And after that I was in contact with the diode for the test.
However, the diode did not respond.:cryyy:
(The diode is a new one.)
This was my first soldering though.
but I thought I did it...
I think the driver pill and brass ring are doesn't match each other.
see this pic
what is the right position?
this is not fit:(
I've assembled upside down, but it does not fit too tight.
(It almost does not fit in Pill)
Is it defective product?
