    Default Current advice

    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

    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..

    i ordered also from him
    and some cheap BR diodes
