Purchased from eBay, us$4.61 including shipping.
I need to run them 12 hours at a time, overnight for a project.
Due to the low price these do need a few seconds to warm up.
Once warm they behave as normal.
They start dimming when the case get to 28+ degrees.
Case is diameter 13.75mm. I only have a 13.5mm drill bit so a little pressing with the vice get's it in there.
I could also have scrapped off the rubber black coating for better heat transfer/fit.
Or used a smaller/no heatsink and fan.
Being battery powered why waste energy when you can go passive.
Will also be quieter.
While they many only seem like toys with 5mW of power they are still dangerous due to the concentrated nature of the beam.
Keep away from eyes and planes.

Just make sure those green laser aren't pointing at anyone's eyes. They are not toys...
