Do you're heatsinks REALLY need to be that big :
It would be cool if that heatsink was made of copper, and you had a Meredith Module in there 8-)

How do you squeeze 500mA out of a Rkcstr?

Interesting. Does a "fixed" setting generate as much heat as an adjustable cranked all the way up?

Limiting the heat generated at these high currents is a good thing.

Maybe Ryan will pop in here.

Default Re: 500ma MXDL Red Laser

why would you set current so high just to reach 300mW of red? This will kill diode so much sooner regardles of this heat sink. Efficiency drops so much after 450mW. Might as well leave it at 450mA and have solid 290mW even with $5 lens...

Is this an LOC or an LCC?

I don't know how long (or short it )will live even if its LOC diode at this current. What duty cycle do you suggest?

Have you tested this diode with 500mA for durability before?

Actually I've had the Long Closed Cans perform better than the Long Open Cans. On the two I tested, the knee didn't show up until 480mA.
