What are you talking about? lol almost every PHR i've had has been no less than 135mW even daguin had one at 200mW which has lasted months and isn't dead yet I don't think? 100-120mW is fairly average for a PHR...

You're crazy... :
Do you have an LPM?
BTW, Dave doesn't have a 200mW PHR that isn't dead yet. You overestimate those wimpy little diodes...
100-120mW is the maximum for most PHRs.

well the diodes are pretty inconsistent some can handle >150mW with no problems some cant even squeeze out 60mW before they die

Nope.

6x diodes give about the same power at any given current.
LOC diodes give about the same power after the current hits 400mA.
SLD1239JL-54 and LCC diodes are less consistent, but they are still very consistent.

PHR diodes are by far the most inconsistent diodes i have ever come across.

I bought one of these diodes from Susie and managed to collect a little data before finally killing it accidentally.. :-[

Here is a Current/Voltage/Power out (After acrylic lens):

LOTS of lasers!

Honestly, I am not addicted to lasers; I can turn them off any time I want to.

It died at about 210mA?
Well, then i would rather keep using 6x diodes.

Kage;

Thanks for plotting both the charts.

Was the temperature increase in the second chart with a normal sized heat sink ?

How did you accidentally kill it? From the graphs it doesn't look like it was ready to die.

I agree, what did you do to kill it?

Well with no 6x's in sight, these diodes may be the best we have.
