FYI, AUG_DTR said all modules are 1.0 to 1.5mm longer (total length of both halves screwed together) with diode installed.ok, thanks!.
AUG_DTR wrote back and said the 35mm module is 30.5mm long with diode installed.
Is it safe to assume the 20mm and 25mm module with diode installed is also 30.5mm long?
Just making sure.
