Hi @Simon_Mao
I discovered a flaw with the 7 mm 3535 centering ring / gasket.
I does not center the LED properly. I discovered this with SST-20 in SMO S2+ reflector already. Please fix this as soon as possible, since the beam with the SST-20 was affected by this off-center LES. And more important: it could damage the LED substrate if lateral force is applied by this ring.
With OP reflectors this does not affect the beam, but it is still not good at all.
The ring used in my S2+ fits more for a 3.75 mm LED; not 3.5 mm. Maybe the B35AM could be used with this ring (3.65 mm), but not the 3535 types.
