I'm about to buy some open can diodes from a LG 20x burner.
I believe these are the long-die type open cans.
I've seen people use these in pointers with currents of aroud 450mA (!)
Of course I'm not interested in pointers
I'm curious what is a good current for these diode to run safely and have a long life if a projector setup.
Anyone? :)
i have also just purchased 6x open can red diodes.
have done a small bit of testing in the past.
im hoping to run these at 250mw in a scanner
What current do you think is safe?
I'd be happy with 200mW per diode if that meant improved reliabilty
nbot sure not received them yet
but will let you know
Did you buy them from tommy G?Quote:

Define long life. I just had an 18x diode die on me after ~200h of use at 365mA. If you want >1000h of lifetime you should run it at the current that gives it its rated CW power, but expect it be 200 mW or less then.
That's also something i was wondering about. I've never been able to find a datasheet for the open can diodes, so i don't know what CW powers are. 200mW would definately be ok for me, I've got a PBS to join 2 together for 400mW with a tight beam.
That must be tommy Ngyen something..Quote:

I'm running my open can at 400mA and it's doing about 260mW... seems fine so far but as tocket said, it's all about your definition of long life. For the price of these diodes, one can usually afford for them to only last a few hundred hours before replacement.
I get what you are saying, but it's more of a reliability issue than it is a price issue for me you see :)
