id like to see your LPM graph of your 400mW 660nm @ 600mA.

mine LPC-815 is set to 500mA and I am scared for it's life

Yeah, if you run an LPC-815 at more than 420, you could be shortening its life...

Sorry dude, no LPM yet.. my readings are based on LPM Results posted in the threads which i mentioned earlier, giver or take 5-10mW eitherway the Po.VS.mA Chart would give a same curve.. Im just playing with the current(mA's)
Yes sir, It does die but lives bright aswell.. such a pity it has to die!! lets see when mine goes led.. a total of 1 hour~1h.15min used uptill now.. Still alive and kicking..660nm @ 650mA?!
No worries, unless it is heatsinked and used for 1min on 30s off DCy..mine LPC-815 is set to 500mA and I am scared for it's life
I use mine for 3~4minutes @600mA but offcourse the heatsink i'm using is an overkill even at that current..
Roger that!!

Kind of refreshing actually. I like the "live hard, die young" attitude. :evil:

So, some time has passed... The LPC-836 has been out for a while now and can be found in expensively on eBay.
Is there a consensus on which is the better diode?
LPC-815
LPC-826
LPC-836
Any general thoughts?

826 is the best IMO

Actually, any one of these three would give you ~300mW at 425-450mA ,
lpc-826 would be the better choice because it is more efficient +25mW than 815 at same current! but if u use the 815 at 460mA it would be ok aswell...

So no one seems to like the 836? Are there any oter hood 650-660 diodes that aren't >$100 out there?

I'd pick an 826 any day. 250mW of red is perfect IMHO. But the 815 is classic and you feel accomplished after dissecting the sled and implementing it into a build. I think the 836 will be for those "special" builds where you want a higher power red but don't wanna buy a 635nm diode.

Any other interesting reds out there? I like single mode cw diodes with circular or oval dots. I see a lot of Mitsus on EBay that I am not sure what they are...

you can get the Single mode ML520G55 635-638nm on ebay, they are pricey tho.
same deal with the HL63133DG by Opnext.

Yeah, at 150mW or more and 638nm they ought to be pretty bright. I'd like to see their beam/dots to compare.

beams and dots are about the same divergence wise.
