hello everyone, recently i bought a 445nm 120mw module from ebay,it is a single mode so first thing that came to my mind was that it uses an Osram PLT5 diode and also was the reason i bought it.

when i recieved it and powered it was definetly a nice singe mode beam and the output was true 120mw.it had a plastic glued lens that when i took off i saw that the diode is a 3.8mm diode and not 5.6mm as the plt5's are :thinking:

after that i tried to unscrew the back half of the module and manage to break both pins of the diode by twisting them :banghead:
after that i ready to thow the damn thing i thought to try my soldering skills, first i bridged the + with the can of the diode(the easy part) and then i was keep trying to solder the other pin,it took me alot of atempts and after half an hour i managed to solder it and secure it with hot glue.:wave:

now its fully working again but im wondering what single mode diodes on 3.8mm cans are available? somewhere i think i read that there was a plt5 revision the was in 3.8mm package but i cant remember well and i cant find it.

How much did you pay for it on eBay? They want 27 pounds sterling for that diode. If it wasn't much, it might be worth having.

hey Paul,only 11$ around 2 months ago,it was an awesome deal for single mode 445nm blue including the driver :)

Yeah, that's quite a bit more than $11.00. I was looking at just the diode and can have it for $24.00. But, $40.00 for a module and linear driver is too pricey for me.
