Lpc836 ?

[rhd]

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

it looks like you have to get 200 eh

 

[rhd]

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

200pcs... Groupbuy?

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.

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]

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

 

[foulmist]

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]

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

 

[regalis]

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]

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]

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

Hopefully this helps you alittle.

Correct me if i am wrong..
heres what i posted earlier.. on a resembling thread which i would like to simplify their differences, here ...http://laserpointerforums.com/f50/hotlight-lpc-826-550ma-380mw-65365.html#post1013608
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
http://laserpointerforums.com/f50/lpc-836-some-results-68104.html, 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..
