Lpc836 ?

rhd · 10-09-2011, 04:38 PM

This is perhaps not as thrilling amidst the exciting news about Mitsubishi 300mW 635s, but has anyone played around with the LPC-836 reds yet?

They're claimed to be capable of 50mW more than an LPC-826:
LPC836 Red brand new Diodes

bennett326 · 10-09-2011, 05:15 PM

it looks like you have to get 200 eh

rhd · 10-09-2011, 05:26 PM

Well, from Laser-XH perhaps - but there should be other sources (or sites that will buy from them and sell on a smaller basis)

jnhowett · 10-09-2011, 05:26 PM

200pcs... Groupbuy?

icecruncher · 10-09-2011, 05:54 PM

If they are the same series they should have much better beam specs compared to the 300mw 635s.

They would be great for some applications. I wonder how much more expensive they will be?

I mean if you can get about 250mw with an LPC-815 and maybe 300mw with an LPC-826.

Cost is about $7 for the 815 and 10-15 for LPC-826.

If they are $25-30 each they aren't worth it in a cost/mw comparison unless you REALLY need just a little more power for a projector or something.

If they are similarly priced to the 826 that would be great.

Wolfman29 · 10-09-2011, 05:54 PM

Yeah, that's actually not bad. I am sure some of the bigger sellers here like DTR, Greg, and others will purchase some of these in quantity and start selling for just a bit over the per unit price they got.

Ghostchrome · 10-09-2011, 05:54 PM

hmmm very cool. I wonder how much they are going to charge.

foulmist · 10-10-2011, 05:25 AM

hmm I just contacted them and for 200pcs little box they want $7.5 a piece...

the guy/girl I don't really know

said that this is promotional price, otherwise is $10.5 a piece...

the power rating is 380mW at 660nm..,.

I asked them for a datasheet but they either didn't see it or don't have any

Ghostchrome · 10-10-2011, 05:59 AM

I guess if you just gotta have that extra 80mW of 660, but meh.

regalis · 10-10-2011, 11:57 AM

For $7.5 i would take one or two..better two because i'm THE diode killer

LPC-836

Now is your time to get some for testing

lazeerer · 10-10-2011, 07:19 PM

Ive got some Coming from my supplier. Will be Here Early next week.

Trying to get a Datasheet for you guys. My Hopes are Low on this.

I think half the fun is just the anticipation of finding out what these diodes really are.

cheech226 · 01-04-2012, 09:15 PM

i bought one of these from rayfoss. should be here in a few days. never could find a data sheet.

LPC-836 Some Results...

sinner · 01-04-2012, 11:09 PM

Correct me if i am wrong..
heres what i posted earlier.. on a resembling thread which i would like to simplify their differences, here ...Hotlight LPC-826...550mA....380mW
I have been experimenting with GSA-H55N sleds, they are by far the best ones that can be extracted from the DVD's, It is a mitsubi$hi diode AFAIK LPC-815.. I have One running at 400mA, Other ones at 480mA, and 600mA..
I made the 600mA one in the Copper-core cpu heatsink just a couple of days ago and it has an amazing beam with just a regular acrylic lens..4 Minutes in the run time and the copper core temperature increase from 70F(ambient) to 80F.

Now, I heard last year some Polish members of our forum were running them at 600mA too and they worked nice and strong when properly heatsinked , and upto 750mA they tend to live but for a short time..

Other ones LPC-826's which are a "tiny bit" more efficient with optical output of not more than 20~25mW than LPC-815's on the average.. Which is not much when you compare the beams & burning power.. but on the LPM side the LPC-826 wins by 20~25mW's.
Since the LPC-826's tend to live for a short period at 550mA so rather kept safe at 420mA like LPC-815's, and LPC-815's for longer period at 600mA with "same" Optical Output, I think there is a general misunderstanding of these and practically there is "NO" difference but the only difference there is , is Technically/Theoretically..

And LPC-836's are definitely not as much powerful too
LPC-836 Some Results..., SO, More or less they all are same, The only difference which could be possible is because of LPC-826's being new and unused hence efficient "a tiny bit more"
LPC-836's just a new market name with no serious improvements.
We can say 400mW red is here ..but running them at 650mA as im doing is simply an overkill..

Fiddy · 01-05-2012, 01:56 AM

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

Ghostchrome · 01-05-2012, 03:20 AM

660nm @ 650mA?!

foulmist · 01-05-2012, 08:12 AM

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

jason66823 · 01-05-2012, 08:32 PM

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..

No worries, unless it is heatsinked and used for 1min on 30s off DCy..
I use mine for 3~4minutes @600mA but offcourse the heatsink i'm using is an overkill even at that current..

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

tsteele93 · 02-26-2012, 03:10 AM

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?

Fiddy · 02-26-2012, 03:36 AM

826 is the best IMO

LPC-826
lPC-836

Any general thoughts?

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...
