Yep this is what they sent me to show you what I mean. Maybe they have got it figured out by now as I did let them know.

Hello all-
Newbie here. I was interested in building one of these into a lab-type unit (current-limited bench supply, fan-cooled heatsink) for use around 1W. Can I expect a decent lifetime in this type of setup? Can these be switched on and off (say 10Hz rate) without damage, or will inrush current kill them?
Thanks,

I've been running mine at 666ma with no issues. It still lives !
I know. I hadn't named the build yet and had tested the diode. I knew I wanted to set my drive to 660ma. While adjusting the drive it hit 666ma. I decided to leave it there and call the build "Mark of the Beast". Seemed appropriate. I had just sacrificed a blue ray burner and the thing will burn the Devil out of you.
There is always madness. I always think I have a method for it. :crackup:LOL ....I knew that was method to the madness.
Cool ! That should be a fun shoot. Can't wait to see the pics ! I need to get off my butt and back to the bench and taking pics. Been kind of busy with house and work stuff.I'm planning on doing another round or two of the lab-stand type photos this summer and definitely want 405nm to be in the lineup. The host, more than likely, will be a C6 with copper heatsink. With that in mind, how much heat do these put off at 600mA and what duty cycle are you using with that current? Is the heat at 600mA substantially worse than at, say, 550mA or even 500mA?
That is the downside to the rainbow photos: they require long on-times (minutes) for the lasers due to having to aim them, and then take the shots. I'm not worried about anything that I have now, and not really worried about common 532nm modules being an issue either. But these 405's, they're the ones that like to die a lot, so hopefully I can avoid that.
But that is one of the planned purposes for my not-too-far-off 405nm build. 550mA seems like a good balance to me, what do you think?
If I want a 1W 405nm I can just build that later as a separate project.
