I would like to try installing diodes in my O-22 switch lanterns and controllers, to drop the voltage and prolong bulb life as per servoguy's postings on the three-rail forum.  Problem is, when I research them what's left of my brain clogs up, there's just too many and too many kinds, and very few places list the sizes.  Servoguy suggests 50 volt minimum, and I figure they should be small, but after that I haven't a clue.  Can anyone recommend a specific diode (or diodes) that might fit the bill?

 

Thank you.

No kiddin'!  10 O22/513*, 3 bulbs each, that's $120 led bill.  I'll pass.  Got the 100 diodes John recommended coming, lost in Michigan right now courtesy of USPS.

 

I have a question as to where to install them when they arrive.  Looks like the one for the switch lantern will have to go inside the switch motor, but the schematic suggests that the controller diodes can go between the two outer posts and the center post on the switch motor.  Where do the "experts" put theirs?  Thanks.
