PHR-805 405nm diodes, replace PHR-803t's

Has anyone yet tried out the new 405nm diodes that are the replacements for the PHR-803t's? If not - I have. These litte buggers are nice, they come NOT in any heat sink, ready to press fit into an aixiz module. Greg at stonetek.org was kind enough to donate a few of these new diodes to me, and I tested two of them to the death!
Here are my results from the first two diodes I tested, each diode was press fitted into and Aixiz module, and thermal grease was applied and then I inserted the module into one of Greg's Blu-M heat sinks. The results are from the using an Aixiz Glass lens first and then diodes raw output... I'm impressed with them - and thank you so much Greg for the extra freebie diodes for me to use and abuse at will!!! I would personally feel quite comfortable running these at 130-140mA as my heat sink didn't get warm until 150mA on up, and the diodes were ran for several minutes a piece. 130-140 gives you a bit more than the 120mA most people like to set their 803t's at. This is just my opinion, I have not done extensive testing on the longevity of this diode at that power level. If they LED at 200mA, 70% of that is 140mA, which could be a good RMS power setting for these - but as we all know only time will tell. I think these diodes have a good potential, and will be more popular even the 803's simply b/c it comes ready to install in the aixiz module, the diode's pins are nice and straight and LONG so they're a breeze to work with, even for me! :yh:

Be sure to pick up a few from Greg, he has a bunch on hand at the moment...

Nice write up Clif.
150mW of 405nm for that price is pretty damn good!

-Tony

Yes these look like they could be winner at that price.

Looks like we have a new cheap 405nm that puts out some good power.

Thanks for the test.

New budget blu-ray diodes FTW

Yeah guys - one little tidbit I failed to mention is that the pin out on these babies is like the LPC-815's, where the case pin is the negative connection. Never seen a 405nm diode with that. When I connected my first one to test, nothing happened, so I thought, ok a DOA. (or I zapped it?) But then when the second one didn't fire off, I said wait a minute, then I got with Greg about it, and we tried out the case pin for a negative and bam it worked. The manufacturer gave him the same pinout as the 803's but this was not the case (if you'll excuse the pun!). It's not a big deal so long as you are aware of it, but something to take note of if you plan on using a microboost driver or other ground input isolated driver, since connecting a negative lead to the former negative pin now does nothing.

Maybe someone with some graph plotting skills might even make a nice little chart for us with the info obtained thus far.
I tried to get my better half to do it but it keeps getting put on the back-burner...

there ya go

Thanks anselm! Nice job.... what program did you use to make the chart? I'm terrible using excel - which is why I haven't done one... I plan on killing at least one of my one PHR-803t diodes doing the exact same test for a direct comparison on the same power meter, heat sink and driver... then we will see which one has more output at the same current, etc.

Ewwww, microsoft....
I use free stuff like openoffice in this case, thank you very much!

Can we do a group buy for these?
btw clif, you, taking the time to do these tests, its much appreciated

I have 90 in stock - if you wish to purchase in bulk - email me with requests.

Anselm - THANKS for doing that - I have already popped your chart up on my site (without asking YOU !) if you want me to remove it, I shall, just say the word - in EITHER case, thank you for putting it into an easy to see format

The Pin out is like a LPC. Man thats weird. Is this the first blu-Ray with that kind of Pin out.?

SenKat_Stonetek :gj: in getting these.

Nice find. These are almost like the 6x blue rays. Much cheaper too. I will still use a PHR-803t for my coming build, but I will surely use this for the next for an extra 50mW over the 100 from the PHR-803t at 100ma

Yes - it is performing nicely, NOT as nicely as I had hoped - but still better than the PHR-803's....AND the 803's are history, folks....all that is left at various distributors will be old stock, and will NOT be replenished ! So - don't count on being able to buy the 803's for too much longer - my favorite distributor has run out of them, and is not going to bother looking for a new source, especially since finding these as EXCELLENT replacements !

The only BAD thing about them is, I have to order them in 200 piece segments - the 90 I have left are the result of a special order for a customer that needed 100 units, so I'm stuck with a LOT tied up in inventory now

Hey nice to see that someone else did the murder test for me. Greg was gracious enough to send some out to me as well...i was planning on doing just this. Phew, lucky me now i can keep my 805's to play with instead of murdering them...+1 to you clif. I do a nice fully built laser review of these diodes once they arrive.

I was nice enough ? PHAW ! YOU were nice enough to not murder me when I completely dropped the ball on your order !:thinking:
When I DO screw up, it's pretty darn good, too !
