You shouldn't hook your diode directly to the case unless your very sure of what you're doing. Usually the driver has two separate +&- terminals. One for the case input and the other set for the diode output.
Usually the driver isolates the diode from the current and voltage in the actual case.
The green module is larger than the red ones because a 532nm laser module is actually an infrared diode and a crystal that divides the wavelength to create visible light.
The red modules just include a red diode.
In my opinion, as ENX said, ebay is your best bet for a small green ~5mW module...
Is the PGL-III-589nm still available?
I'm itching for one of those babies......
PM sent.
Edit: I've got a 12x still packaged from DTR that I can trade to ya as well if you're still in need.
Always remember that you are your own individual. Although it seems impossible to make every decision for yourself after a relationship, you will regain a stronger self control after doing so.
Also remember to appreciate the small and beautiful things around you every day! When you think of...

Received my silver host and heatsink yesterday. Its really cool! Im stoked to stick a diode in it tonight after work... Haha
Re: Laser fire sale Large images
Yeah, I sent payment for one of the hosts and heatsinks and haven't heard anything besides "Payment received". I think it may take a while but with patients this will definitely work out. I know that I got a refund on the drivers last time Kiyo disappeared and...
